With Microsoft expected to launch its second Surface tablet in the coming days, it’s time to start thinking about how or if this device changes things. Stung a bit by limitations in Surface RT, I’m nonetheless still quite excited about Surface with Windows 8 Pro. And if this machine lives up to its advanced billing, it could fulfill Microsoft’s promise to change the PC market for good.
Microsoft first previewed Surface Pro, as I’ll now call it, back in June 2012. Earlier this month, it provided bloggers with a few minutes of hands-on time at CES, but since I declined to attend the show, I will need to wait a bit for my own hands-on experience. Fortunately, I have a few insider secrets about Surface Pro you won’t read anywhere else.
Here’s what’s happening.
Form factor
While I previously compared the specifications of Surface RT with those of Surface Pro in Microsoft Surface: RT vs. Pro, a Specifications Comparison, I’ve now spent over two months using Surface RT and have a better idea of how portable the device is, and how the slightly bigger and heavy Surface Pro will compare. Put simply, the Surface RT and Pro are almost identical looking from a form factor perspective, with the Surface Pro’s slightly thicker body--.53 inches vs. .37 inches—being the prime differentiator. (The reasons for this difference are discussed below.)
Where the Surface RT and Pro differ more obviously from a form factor perspective is the weight: Where the Surface RT comes in at just 1.5 pounds, the Surface Pro weighs 2 pounds, fully 33 percent more. Now, 2 pounds is still very light, and when you factor in the weight of a Type Cover or Touch Cover, the device is still lighter than the 11-inch MacBook Air. (It’s also infinitely more versatile, but that’s another story.)
Microprocessor/graphics/RAM
Where Surface RT features a 1.3 GHz NVIDIA Tegra 3 (ARM) processor with integrated graphics and 2 GB of RAM, Surface Pro features a more conventional and well understood 1.7 GHz Intel Core i5-3317U processor with integrated graphics and 4 GB of RAM. This combination graces a huge percentage of common Ultrabooks and will represent a huge improvement over the Surface RT’s netbook-like performance.Indeed, a peek at System properties reveals a score of 5.6 on the Windows Experience Index (WEI), with the processor coming in at 6.9 (out of a possible 9.9); the primary disk rates a stellar 8.9. Windows RT doesn’t provide WEI numbers, and for a reason: With that OS, Microsoft promises a consistent experience, so no WEI score is required.
One big area of concern with the Surface Pro is that the Intel Core processor requires a fan and thus the system could be loud. Well, Surface Pro comes with two fans, but in normal use it’s almost completely silent, and uses a unique vent that runs along the back edge of the device; this explains the additional thickness compared to the Surface RT. Play a modern game, however, and the fans kick in, as expected.
The Surface Pro also sports a much higher resolution display than the Surface RT, 1920 x 1080 (“full HD”) vs. 1366 x 768. I’m a bit nervous about how the Windows desktop will look on the Surface’s small 10.6 inch screen. But the Pro will provide better performance and higher resolutions on an external display; that the Surface RT can drive a full HD external display well is perhaps a good sign. Oddly, the Surface Pro uses Mini DisplayPort for video-out, where Surface RT uses a more standard mini-HDMI port.
Battery life
One of the absolute highlights of Surface RT is the battery life: This highly mobile wonder gets about 9 hours of battery life. When Microsoft vaguely admitted that Surface Pro would only get “about half” the battery life of Surface RT, people panicked. But in real life, it’s not quite that bad. Surface Pro gets over 5 hours of battery life in real world use, not commendable in any way, but not a complete dud either.Ports and expansion
With its nearly identical form factor, it should come as no surprise that Surface Pro works with the same Type Cover and Touch Cover keyboard covers as does Surface RT; they share the same cover port. Where the Surface RT features a single USB 2.0 port, the Surface Pro has a single USB 3.0 port, plus a second 5 watt USB port on the power supply for device charging. Both devices have micro-SD slots, and a headset jack. As noted previously, where the Surface RT uses micro-HDMI for video out, Surface Pro uses Mini DsplayPort.Pen and touch support
Where Surface RT only supports capacitive pens, which emulate a fingertip in a smaller form factor (which does provide slight better accuracy), Surface Pro supports true electromagnetic pen/styli. Indeed, it comes with one: The bundled pen supports multiple pressures (for thicker lines), an eraser, and a right-click button. It also features a weird magnetic latch, identical to that on the end of the power adapter, so that it can connect to the exterior of the device when you’re not using it. This seems destined to be lost, but the Surface Pro wasn’t thick enough to provide the otherwise preferable internal bay for the pen.
An electromagnetic pen requires a certain kind of digitizer on the screen, and sure enough the version on Surface Pro is indeed superior to that on Surface RT. It’s also better at multi-touch: Where Surface RT supports five touch points, Surface Pro supports 10 touch points.
