The Surface Pen

While you don’t get a keyboard with Surface Pro, Microsoft does bundle a digital pen with the device. Based on Wacom’s technology (presumably Electro-Magnetic Resonance), the SurfacePen supports 1024 levels of pressure sensitivity. The pen itself is passive, all of the power consuming circuitry is contained within the display stack itself. A weak EM field is generated by Surface Pro which enduces a current in the digital pen that then powers its resonance circuit, which in turn impacts the EM field and is used to determine the position and angle of the pen itself. Surface Pro will recognize the pen starting from about an inch above the display. The pen won’t work on Surface RT as the requisite Wacom EMR grid and logic don’t exist on that tablet.

It's not clear to me whether or not Microsoft is using Wacom's RRFC to enable capacitive touch in addition to digital pen support. Regardless, I didn't notice any impact on touch response when using Surface Pro without the digital pen.

The Surface Pro pen doesn’t store anywhere inside the device, but it can be docked to the magnetic power connector as long as you’re not charging the tablet. The magnetic dock doesn’t charge/power the pen in any way, it just holds it in place. The tablet is a bit awkward to hold with the pen in place, and there’s also the problem of where do you store the pen if you’re using the tablet while plugged into the wall, but I suppose it’s better than nothing.

Microsoft does a good job of palm rejection with the pen in use, although I did occasionally have to erase an errant line or two caused by the edge of my hand in a drawing app.

Tracking and responsiveness were both excellent in using the pen. I’m not much of an artist but I did have a good experience sketching with Surface Pro’s pen. Creative professionals who are already Wacom users will probably appreciate the inclusion. Surface Pro doesn’t really offer the same drawing surface area as some of the larger Wacom tablets, but I can see how it’d be a nice addition for those who don’t want to carry around a separate drawing tablet.

You can configure Surface Pro to work in second screen mode, allowing you to use the entire display as a pen surface while using the integrated miniDP out to drive your display to an external monitor. In this mode Surface Pro approximates a Wacom digital tablet, although without the software customization that you get with those tablets. The biggest issue I had in second screen mode is the lack of a toggle to switch between pen and mouse positioning, Surface Pro operates exclusively in the former.

In pen positioning, every point on the Surface Pro display corresponds to a similar location on your external display. To draw something in the upper right corner you need to move your pen to the upper right corner of the Surface Pro display and draw there. Wacom’s own tablets let you switch to mouse mode, allowing you to use the pen as a mouse to place your cursor wherever you want it. Pen mode is something you may or may not be able to get used to, but it’s worth pointing out that the inflexibility is a limitation of Surface Pro’s pen implementation.

    God forbid you have to play games just like

    oh my god

    every other device has to play games

    People that want to play battery killing games are obviously going to carry a secondary charger with them, as well as a halfway decent portable keyboard/mouse. This is a limitation EVERY "mobile gamer" would have to deal with, not just one who has a Surface Pro.

    That is what I am talking about, not play touch based games, unless baldur's gate gets ported to windows 8. Or even carry an xbox controller with you when you are on the go! There are a lot of games that have seemless controller support(with other games that don't). You can even search steam for games with controller support. I am by no way implying that this is a gaming machine, but it will work quite nicely with the rise of a lot of indie games, and older games with controller support. A lot of games on steam backup save files to the cloud so you don't have to swap save files around from one machine to the other. This is just my 2 cents, sorry I was not as clear originally.

    So, thought I'd chime in and mention the fact that most games require you to just click on the screen, and maybe use some hotkeys. But plenty of games are purely mouse driven, and for those, touch translates beautifully.

    Gaming benchmarks in general seem to have been missed, we could have some graphs and numbers.

    Still looking forward to the case where we can plug in a tablet a the end of the day to keyboard, monitor and mouse and just use it as a desktop. Almost could do it for this, just a bit cumbersome not to mention space management would be a pain.

    I agree. It's the only thing missing from an otherwise perfect review.

    I'm hoping that the Surface Pro get revisited as a portable gaming PC. I'm obviously not talking FPS, but League of Legend, FTL, and others would be games I'd like to play on the go.

    If you want to understand a gaming performance, look at any ultrabook review. Surface is not going to be magically any different, except that you should not expect to go very far on battery alone and once you connect it to the charger, one of the biggest advantages of Surface (portability) vanishes.
    The Ivy Bridge CPUs come with Intel HD4000 GPU and it is OK for older games (2009 and earlier) and only on reduced resolutions and medium to low settings.
    My personal experience gaming on ultrabook:
    Skyrim - no go
    Fallout: New Vegas - on reduced resolution and minimum settings
    Bioshock - reduced resolution
    Medieval Total War - medium settings + reduced resolution
    Civ V - minimum settings, no need to reduce resolution (and it is touch friendly game, hurray!)
    Sorry, I don't play shooters or auto racers, so can not comment on these.

    Skyrim is playable on the surface pro on lowest settings at 720p. plays pretty well given the limitations.

    Baldurs Gate Enhanced works fantastically on these devices. Granted its' not "high end", but it definitely shows how cool a game like that can be on a touch enabled device. Give it time.

    This review is, far and away, the best review of the Surface Pro I've seen of the 15 or so I've read. The other reviews all mostly regurgitate the same exact information; It runs fast, it has Ultrabook specs, it has "poor" battery life, it can't sit on your lap easily, It's too thick/heavy to be a tablet, so on and so forth, all the stuff we've known for the past TWO MONTHS.

    The only thing I felt was lacking between all the graphs about color calibration and wifi range and whatnot was how altering system settings would change your expected battery life. For example, assuming the battery tests were being done @ 1920x1080 with ~65% brightness, how long would the battery last if you turned it down to 1600x900 @ 40% brightness? How does the battery do with WiFi turned off? Can we expect significantly better battery life if we stay away from a desktop internet browser?

    Obviously, making compromises isn't supposed to be what the device is about, but I wouldn't mind doing a little bit of power management if it means I can consistently get 7-8 hours of battery out of it.

    Outside of that though, fantastic review. The WiFi speed chart blew me away; I would have NEVER assumed there was going to be that large of a gap. Really unique info in this review that other reviewers would have never thought of to work out, a lot of which is lowkey important in how the device is going to be used on a day to day basis.

    This is a clear compromise product. Awkward to use as a laptop, awkward to use as a tablet. You know what happens to compromise products? Well, just ask Microsoft with the RT they just released.

    They fail.
