Yeah - I thought long and hard about what I actually wanted a tablet for and decided that the Surface RT would pretty much do everything that I wanted - and I was right. Had the original Surface RT for a little while but found it a bit slow and sluggish so I returned it and bought a Surface 2 RT. The ability to use IE, Word and Excel on the go and to be able to plug a USB stick in is just sheer bliss (my Surface 2 has recognised and been able to copy files to/from most digital cameras and Android phones that I have plugged into the USB port).
You may be lucky that they sent you a Type Cover instead of a Touch Cover. I bought a Touch Cover because I was bit overly focused on the thinness of it. However, I started getting strange problems with the touch screen 'phantom touches' which also affected a number of other users (see
http://www.surfaceforums.net/forum/microsoft-surface-2/8499-problem-my-surface-2-a.html). So, I bought a Type Cover 2 and all of those problems have disappeared, not only that but the Type Cover 2 is for me much easier to type on (as can no doubt be seen from the length of this post) and I can touch type on this nearly as fast as on a standard-sized PC keyboard. The touchpad on the Type Cover 2 could be better: - keeping the left-hand part of the keypad held down while highlighting blocks of text or areas of the screen is problematic for me so I tend to use a Logitech mini mouse most of the time. A minor issue with both Covers is that they flex or bend a bit when I use them on my lap and the cursor can jump about when I am typing - if I use it when sitting at a table, then there is no problem with this at all.
The only things that I miss are FF and Chrome - but IE works fine so it's not a big deal. My VPN provider doesn't offer an RT-based app, - it would be nice to have one but I can survive without it. Might also be nice to have VLC, but the speakers aren't so great on this and so I don't tend to watch much video on it. The Kindle app works fine for me, but the EverNote RT app is not as easy to use or friendly as the Windows 7 program that I have on my PC.
One thing is that it has kind of changed my life in a small way. It's so light and comfortable on my lap and the battery life is so good that I now tend to watch TV with it on my lap pretty much all the time - it's much easier to do this with my Surface 2 than a lap top. Unless I am watching something absolutely fascinating or riveting on TV, then I tend to have my Surface 2 on my knee and keep an eye on things like FACEBOOK and email at the same time as watching the TV - it's probably not doing my ability to concentrate and pay attention much good. Another plus point is that I find that the touch screen and Type Cover work together really well. It has now become second nature for me to use both at the same time. When working with it I simply raise a finger or two to select or resize things on the screen as I write. In fact, when I am at work and using my old-fashioned non-touch Dell laptop I often find myself tapping at the screen and trying to do things with my fingers. I've never really been into serious gaming but the Solitaire, Tap Tiles and Mahjong apps on here are great for keeping myself occupied in long queues, airport lounges etc.
A friend is going to buy a Surface Pro 3 for me and bring it back from the States in a couple of weeks time. I am a bit of a gadget freak and I really fancy the look of the Surface Pro 3. One thing that will be interesting to see is how the larger screen works out. Even though I can easily make things on the screen bigger on my Surface 2 it still happens that I often end up squinting at it and straining my eyes so I am looking forward to having a 12 inch screen. Having said that, unless the battery life on the Surface Pro 3 is considerably better than I anticipate then there will be no way that I will consider getting rid of my Surface 2 RT, it comes into its own on long-haul trips and weekends away etc.
I hope MS continue to support and develop the Surface RT line. If they keep on making it thinner and increasing the battery life then I can see myself buying another model a couple of years down the line. The main improvements that I would like to see are - a better touchpad, a second USB port, better speakers and keep on increasing the battery life. I haven't heard or seen any rumours from Microsoft as to whether they are going to continue to support the Surface RT line.
