I think the fact that there are only a handful of apps for Windows RT right now and that a 32 GB tablet only has 16 GB available for me to use OUT OF THE BOX is a pretty damn good excuse not to buy one. Not to mention the fact that every review I've read says the Win RT tablets are a bit sluggish.
Believe me, I want to root for the home team. I love my Windows Phone and I would love nothing more than to drop kick my Android tablet into space and pick up a sexy Nokia tablet to replace it... but I'm not even considering it until Microsoft gets a little more serious about this and figures out what they are doing with this Win RT thing. I get the sense that they aren't even sure, I see very little enthusiasm in the market and very little development buzz for a product that most people don't quite understand yet.
With my phone it's a bit different, I can sacrifice the availability of some apps and some functionality I might miss out on in order to have the phone I like best with the UI I like best, but I ask a lot more than that out of a tablet.
So yeah, it's a great price, but even if it was $199, a tablet with hardly any apps and half of it's limited memory eaten up by system files out of the box isn't terribly useful at any price.
I am optimistic there is a future for Windows RT once Microsoft pulls its head out of its ass, but we aren't there yet. One sign that has happened I think will be if they drop the stupid name Windows RT. It sounds like an internal code name that they just didn't have time to replace with something more consumer friendly. It's awful and it communicates nothing about what it is to people. What the **** is RT? I mean I know it means Run Time, but does the average consumer know this? It's a stupid name, it needs a name that communicates that this thing runs the tile part of your Windows 8 OS, but not the normal desktop part. Call it Windows Light or something. And for the love of God do a better job of getting apps on it than you have done with Windows Phone.
