I've been reading through this thread and I have to say a lot of people are bashing this product without actually using it. I originally thought the RT would be useless and that I had to have the Pro model, but didn't want to part with that much money when I really didn't need a tablet. 3 months ago my company had me roll out a new wireless network to accommodate a new product we were implementing in our fixed operations departments. This product would utilize the 4th Generation iPad with Retina display and some proprietary apps that would communicate with our existing dealer management infrastructure. After setting up 20 iPads I was honestly disappointed in the overall experience. I'm not a fanboy of any particular company, i'm more of a "right tool for the right job" type of person. I love my iPhone, but the iPad just didn't really work great for me. About a month ago, I acquired a Surface RT 64Gb and bought it only because I wanted to really get a feel for the device. $150 for the tablet, case, and type cover made it a pretty inexpensive gamble.
The majority of my job consists of editing workbooks, preparing pdf and doc files, remote server management, and system preparation. I brought the Surface to work and set it on my desk. Day 1 I used it to stream xbox music all day and occasionally check facebook. Battery life was pretty impressive to say the least. I still had over 20% when I left at the end of my shift. Day 2 I was installing 3 new pc's in another building and swapping out the existing pc's for others in another section of that building. I used the Surface to access the sharepoint site and it worked seemlessly with the files using the included Office apps. (I can't even do that from my mac pro workstation) While swapping out pc's I used the Surface to modify permissions in our content filter, update IP address workbooks, retrieve passwords for email accounts... all basic stuff, but stuff I was doing on the tablet and not the pc I was installing. Day 2s battery life was remarkably better since I wasn't streaming music. 70% when my shift was over.
At home I have an HP Microserver (Windows Home Server) that I store the majority of my TV Episodes, Movies, and Music on. I stream it to my television through a WDTV. I ditched premium cable a while ago, but for the basic channels I needed to rely on comcast still. They gave me a cablecard and I have a PC in my bedroom that runs Windows Media Center. I stream live TV in my living room using the Mediacenter Extender built into my Xbox360. I really wish the Surface RT could at least work as an extender! I'm also waiting eagerly for VLC player to be ported to Windows RT... as it would be the best way to stream media from my Home server. Alas, my Surface is basically a facebook/internet browser when I'm in my living room. I can remote desktop into my home server to check things out as well... this is a nice feature.
Day 3 onward I carry my Surface with me everywhere I go. It's a tool at work that a lot of people who have played with it are actually coming around to wanting one. One of the other IT persons is actually ditching his Nexus tablet for a Surface 2. The surface has a purpose and it fill that purpose very well. Surface 2 is going to sell more, the Surface 3 is going to sell more too. I think a lot more business are going to want employees with a Surface instead of an iPad.
