Battery Life

Surface Pro 2 retains the same 42Wh battery and 48W charger as the original Surface Pro. I wasn’t pleased at all with the battery life of the original design, and I had hoped for a significant increase in battery life with Surface Pro 2. Microsoft claims up to a 75% increase in battery life compared to the original. In our 2013 tablet battery life test that turned out to be a 40% advantage – not shabby, but not where it needs to be. Update: Microsoft issued a firmware update that brings Surface Pro 2 up to 8.33 hours of battery life in our web browsing battery life test, or 76% better than the original Surface Pro.

I’m also beginning to think that Haswell’s video decode engine may not be all that power efficient. We did see better results out of OS X, but it’s still nowhere near what’s possible on the best ARM platforms.

    The Wacom Intuos Pen and Touch medium tablet provides equivalent pen and touch capabilities to the Surface Pro 2 (similar active area with 1024 pressure levels, multi-touch, etc.) and costs $199. Even with the Wireless Accessory Kit it only comes to $239, and you can use it with any Mac or Windows PC you care to.

    The last microSD card I purchased (Lexar 600x) came with a free (and tiny) USB 3.0 microSDXC UHS-I card reader, so I wouldn't place a particularly high value on that feature.

    stop kid yourself.

    drawing on a tablet is DIFFERENT from drawing on a screen. you might as well draw using a mouse...

    drawing on a touchscreen like the Wacom pad (similiar to Pro) on the other hand, allows much much better productivity.

    omg stop kid yourself... so you rather have to bring a card reader with you all the time vs just have it build in?

    fyi, iCrap pad doesn't even have a usb

    Apple doesn't sell any tablet (PC) only their mobile tablets on ARMv7/v8 (soon 64-bit). Modbook does have a USB (3) port, MicroSD/SD, Thunderbolt, Firewire and ethernet port. Plus 1024 pressure levels. It's the mid-2012 MBP 13 though. The third party modification that is. It's still better than some other offerings, has wacom and all the software support. Writing on the screen is more for notes and sketches rather then work though. Having a wacom tablet and an external monitor is what you do for your work.

    Plus your kidding your self if you think this is comparable to an enterprise convertible Tablet-PC that you don't have to remove the keyboard to write or paint on it from Lenovo, Fujitsu or HP.

    Most of my microSD cards live in USB card readers and I use them as I would USB thumb drives. If Microsoft had specced a full size SDXC UHS-I card reader here, it might actually be useful. I'm not sure what the point of a built-in microSD slot on this device is.

    Also, this thread has gone a little nuts, but I believe we were comparing the Surface Pro 2 to the MacBook Air (11-inch, mid 2013) since they are priced the same and use very similar hardware despite the difference in form factor. However, since you bring up iPads, they do have USB, they just use a proprietary connector on the device side. Most iOS accessories communicate via good ol' fashioned USB. Device class / driver / application support is obviously spotty for devices that weren't designed as part of the MFi program, but many HIDs work just fine anyway.

    Air has CRAPPY TN display, no touch screen, no active digitizer, cannot be used as tablet. HD5000 doesn't mean anything - you still cannot play any proper game anyway. Reply

    Actually, the MacBook Air has a very well calibrated TN display with decent brightness and contrast levels and an appropriate resolution for a PC screen of that size.

    Yes, the Surface Pro 2 is much higher resolution and packs almost twice the pixels of the 11-inch Air, but it also ships with DPI scaling set to 150% by default, which makes the effective pixel density 139 ppi, which is awfully close to the MBA's 135 ppi. It also drops the effective desktop area to 1280x720, which is less than 1366x768, and it has 16.5% less viewable area to begin with. Don't get me wrong, I'm all for more pixels, but the 11-inch MBA doesn't have to deal with any DPI scaling that could get messy on a traditional desktop OS in order to provide essentially the same usable desktop area. The Surface Pro 2's screen does go 36% brighter and has a contrast ratio that is almost 50% higher, but uncalibrated dE 2000 values are at best a push with the MBA. The Surface Pro 2 being IPS and all should have a larger gamut than the MBA, but I haven't seen any directly comparable numbers yet as far as that goes.

    The bottom line is that I think both Microsoft and Apple specced the displays they needed to for their respective devices, but Apple is still more aggressive with factory calibration.

    The MacBook Air can never be a tablet, but it is very good at what it does. The Surface Pro can be a tablet or a notebook replacement, but it definitely makes some compromises to fit in that space. Unfortunately, I feel like even with round two, Microsoft is still making more compromises than they need to.

    Pixel density effectively, or non effectively is the same no matter if there is DPI Scaling or not. Reply

    True dat. The point I was trying to make is that MS scales the UI elements by default to be exactly the same size as they would be on the MBA. Of course all the pixels are still there, which works brilliantly for apps that can handle them properly and not so brilliant for many others that weren't expecting a 208 ppi display. I kinda feel like a lot of the reason for wanting a full Windows Pro x86 tablet is for running desktop apps that unfortunately don't handle dpi scaling very well. Reply

    How qualified are you to make such a statement?
    How long have you been using the Surface Pro 2 as a desktop replacement?
