Own a Surface RT 64GB
And I've tried and tried and tried but I just don't like the Touch Cover. I love the device but not the cover so when I go to buy the Surface Pro, I'll grab the Type Cover and have both...leaving the 'touch' cover on the device I plan to use the least which will actually probably turn out to be the Pro. Besides that, I love it. I bring along a little D-Link Wifi AP when I go to a client so I always have Wifi or the ability to connect to a wired only network (think configuring routers, switches, etc.) and I have my Lumia 920 with LTE Internet Sharing. It's really been surprising what I 'can' do with the device compared to what I can't. One of my co-workers called me asked me "is there mstsc in Windows RT?" and I was like "I'm not sure" but it turns out that yea, there is and there's the "Remote Desktop" app in the Store. I knew I was buying something less capable than Windows 8 but I didn't realize how little that amount would be.
The only thing that's irked me a bit is sites that don't display properly in IE10. I don't mean to start a whole 'Microsoft doesn't use standards!' debate but it does suck that if IE10 doesn't render a site properly for whatever reason, that I have to RDP to another workstation in order to access the site I'm trying to reach. I run into this on a lot of network devices. Yes, there's the CLI interfaces but some things are just easier via the GUI's (usually).
Despite that (Touch Cover and IE10), it's really a high quality and certainly very capable device. It convinced me to buy the Pro version as well because well, I like pen input and I'll keep the Surface RT around as my 2ndary (or perhaps back to primary if another browser is released for RT...for the battery life).
