A pretty good (and mostly positive) review of the device here

The Microsoft Surface with Windows RT ($699 direct) is Microsoft's first entry into the wild world of tablets. Priced to compete with the Apple iPad , the Surface tablet with 64GB of storage comes with a 10.6-inch, five-point multi-touch screen. As is, it's aimed at users that want to do more than simply consuming media and websites, with innovative keyboard covers that make some of the more expensive Windows 8 tablets' docking solutions look absolutely clunky by comparison. Plus, it has an ace in the hole that makes it feel like a "real computer": The Surface comes with a full copy of Microsoft Office 2013 (Home and Student Edition). The Surface has the same user interface as upcoming Windows 8 laptops and tablets, thanks to Microsoft's Windows RT operating system. However, since the tablet uses Windows RT and a more economical ARM processor, the Surface isn't compatible with the majority of existing software made for Windows 7 and XP. This is the conundrum we find ourselves in while we look at Microsoft's first true computing device.
