A Plethora of Ports and Storage Options

One area where Surface is a significant departure from the iPad is in its IO and expansion. The iPad features a single dock (and soon to be Lightning) connector, while Surface looks more like a laptop (or Android tablet) when it comes to IO.

There’s no port for syncing, you get content onto Surface via WiFi or a more traditional method. Surface has a single USB 2.0 port on the right side of the device. You can plug almost anything you want into this port, including USB storage devices of course. Behind the kickstand is a single microSD card slot, giving you another option for expansion.

On the left edge of the device there’s a micro-HDMI out port that can be paired with a Microsoft made VGA or HDMI dongle (both dongles have a 22-degree connector on them to mate flush with Surface). I tested HDMI output with Microsoft's dongle and unfortunately the result wasn't very good. The 1080p output had a lot of issues with scaling quality (as you can see from the shot below) and there was a lot of tearing on the screen with a big impact on UI frame rate. I reached out to Microsoft for an explanation but have yet to hear anything.

Finally there’s a standard 1/8” headphone jack along the top of the device.

Power delivery comes via a custom magnetic connector along the lower right side of Surface.

Given that the internal storage is an eMMC solution, performance from the microSD slot with a good card should be fairly comparable. In practice I could read and write a large sequential file at roughly 10.5 MB/s using a SanDisk microSD card.

Copying from a fast USB stick to Surface’s internal storage gave me transfer rates closer to 17MB/s. There are a few vendors for Windows 8/RT eMMC devices, I’ll be paying close attention over the coming weeks to figure out who makes the best. I know Microsoft and Intel (among others) have been playing close attention to the eMMC providers with hopes of weeding out those that deliver honestly unacceptable performance.

While doing background file IO I didn’t notice any of the stalling/pausing that we’ve seen on some of the more recent Android tablets.

Update: Many have asked about how much storage is taken up by the Windows + Office 2013 installs. The screenshot below shows the directory size for both C:\Windows and C:\Program Files, the latter is where the Office15 install files are included (and yes winword.exe is still the Word executable).

You're looking at roughly 6.47GB for Windows RT and then another 830MB for Office for a grand total of around 7.3GB. 

USB Compatibility

Microsoft is particularly proud of its single USB 2.0 port on Surface. Although USB ports have been featured on several Android tablets, their support was typically limited to flash drives, keyboards and mice. With Windows RT, Microsoft wants to bring more of the traditional Windows experience to tablets. Had Surface been x86 based, you would be able to plug in virtually any USB peripheral and it would just work. As the first version of Surface is based on an ARM SoC, driver support is a little more limited but still pretty decent.

USB drives obviously work as you’d expect them to. Even SATA to USB adapters worked fine when plugged into Surface. Other smartphones and tablets also worked, although their level of support varied. For example, you can plug in the iPhone 5 and have it come up as a supported device for moving pictures to/from. However USB tethering is not supported by the class driver included in Windows RT. You can even plug an iPad into Surface and get the same level of support.

Printer support is pretty decent, although the Epson Workforce 910 I tried didn’t actually have specific driver support under RT. Although development for the desktop side of Windows is limited, manufacturers can supply Windows RT drivers to enable support for some more obscure devices. Unfortunately when it comes to those devices you’ll have to play the waiting game as there’s simply not a lot of third party Windows RT drivers available for download today.

    As someone who picked up a 32GB HP Touchpad for $149 and slapped ICS on it via CyanogenMod, I still don't understand the appeal of this kind of tablet.

    To me, it physically looks absolute great, and blows any iPad out of the waters (but, to be fair, I never liked Apple's designs), but I still don't know why one would buy a $5-600 high end tablet. Why not a compact laptop at that point? We're clearly far beyond a few mobile games, youtube/720P videos and ebooks. Don't tablets make more sense at the lower end?

    For $149, I've gotten a hell of a lot out of my tablet, but these are on the edge of ThinkPad X-series territory.

    That was a fire sale for way bellow cost so it doesn't really apply to current pricing.

    Tablets don't replace portable laptops, just another option. Both have their trade offs and fit different users, for example my Mom. Many users also have a tablet in addition to a laptop.

    Tablets offer multi-touch for games and relaxed use, battery life, portability, simplicity, and screen quality to name a few benefits.

    The firesale was part of my point, but that general price bracket also now exists as a regular part of the tablet market.

    The things you mention at the end are what I see them do as well, but where does the 500+ dollar tablet fit into that? Unless you want some ultra high definition on that screen, those needs are filled quite well by cheaper tablets.

    I would agree with you but at $499 or higher apple is moving millions of tablets so clearly other people do not seem to think that way. Your comments are basically neither here no there. The usefulness of slate tablets is a side arguement, I do not own them as you said because I would rather just have a real functional laptop. But part of the greatness of windows 8 is that it will finally push vendors to not so much jump into the tablet market but actually functionally merge the laptop and the laptop to a point where they become one device and no one needs to make a decision about one or the other or carry both.

    Do you really think its a mass market to hack tablets?

    This is a product for non-nerds and Office.

    (Hint: When you get older you will stop caring about hacking stuff. You want thing just to work. After working 8 hour with computers you want to come home to a computer setup that works. Including that all you family and friends have working stuff since you are support 24/7 for them. Many IT professionals like me solves this by just buying a bunch of macs and hand them out. "now it works. Don't call me for support".
    Building you own PCs are meaningless. You have 1000 dollar extra to buy an Alienware. You also will be interested in pussy. Beautiful designed stuff (like Apple stuff) attracts pussy. And I like pussy even if I am married. (*hint2* never get married). Hacking stuff is a pussy repellant. If they see a home built PC or strange Tablet with strange OS. *poof* pussy gone.

    This may be the dumbest thing I've seen somebody say on the internet. Specifically the last paragraph.
  • superflex - Wednesday, October 24, 2012 - link

    Or the most brilliant.
    I concur with the OP. Who has time to fuck with flashing ROMs and installing modded OS's. Would you rather OC your CPU and memory with a new BIOS or be hitting some strange?
    I've built plenty of PCs but now the last thing I want to do is go home and fuck around with making sure my OC temps are stable or I have the highest benchmark score.
    Get a life dude. Pussy rules!

    Yeah, because women just love the sort of person who says "pussy" repeatedly. In the comments of an article on a tech blog.

    Seriously, if you don't like tech, then what the hell are you doing here? Go annoy some people on some pussy blog somewhere.

    You sound like you didn't get out of your mom's basement until you hit 21 when your friends eventually got you out to a bar. They hooked you up with a drunk broad so you can finally lose your virginity. Now you're a self-proclaimed frat bro with mad game.
    Hint: normal, developed adult males don't act like a 12-y.o. girl getting the new Justin Beiber CD at the sight of a frisky female. "Pussy" is just something that happens, they get it like they get their coffee in the morning - it's a normal occurrence or even convenience. Remember how, a couple of years ago - in high school, you couldn't stop bragged in class about your dad's sick new Mustang? Well, it's not like that. Bigger things excite grown-ass men - hobbies, jobs they love, personal projects... shit, even politics. And to some, computers and electronics are one of those things.
    But, anyways, you'll get it. Eventually.

    Anand, do you know if Microsoft organically grew the hardware unit that built Surface, or did they buy a hardware team and integrate it into MS?
