I have a Surface RT. There are times that I'm frustrated with it and there are times I'm happy with it.
First off...the 64gb model is a waste. You're not going to use up the space at all.
It is cheap for the memory, but Apple while more expensive actually results in you actually using all of the memory.
So get the 32gb model...
Updating it is a pain. Like, when I first turned it on and updated it, it must have take like 6 hours to fully update. Seriously.
You're going to be using official MS apps for the most part. I haven't really run into 3rd party apps which were OMG amazing yet.
So what I like about it is that the UI is actually pretty innovative, with the side swipes bringing up search bars for the application. Swiping up is better than the long-press that Android relies on. IE has the address bar on the bottom which is a good innovation IMO, which I'm reminded of everytime I have to reach my thumb to the address bar in android.
The best reason to like it is that
1. it has full microsoft office. So it is a good writing/productivity station
2. it has a full-sized USB port, allowing you to hook up a number of peripherals like mice, keyboards, usb drives
3. it supports flash. This is actually a big deal for me since I like watching shows like the Daily Show online. Apple and Android and SOL on streaming the flash full episodes. Only the RT can do so
4. Feels very solid. Arguably more solid than ipads I've used.
5. compared to the x86 versions, the ARM version is cleaner.
6. Win RT has a desktop file manager which is better than anything from android or apple. Now if only it had programs worth manipulating with...
7. excellent battery life.
Reasons to dislike it:
1. can be slow. Though I compared it to a pro recently and it didn't do terribly.
2. kind of thick and heavy compared to other tablets. Which doesn't bother me too much because it is so much sturdier that I don't worry about throwing it in a bookbag.
I'd also recommend skipping the Type covers which everyone gushes over. The touch cover makes much more sense IMO. For serious work you're going to plug in an external keyboard anyways that's better than the type cover. The touch cover is for the rare instance when the touch screen controls are cumbersome and you need a mouse pointer. Otherwise most of the time it's flipped backwards and is acting as a simple cover.
The one thing I really wish it had was a wacom digitizer like the pro. Maybe in the 3rd version it will.
