Edit: Misread the article, but leaving my post up to show my shame and jumping the gun. Even at the mid $300 price point, this is a bad buy in my eyes - Android simply offers far better options for tablets in this range, and some proper full Windows 8 tablets are coming in around this price. Even with a $150 discount, this limited product is still way overpriced.
Wow, this thread/deal is pretty clear evidence that some people are really letting their hatred for all things MS/Windows 8 get to the point of pure unreason.
Windows RT is a disappointment - not that I ever really had high hopes for it. Windows 8 pro tablets are pretty damned good for what they do, and RT is the lame legged bastard stepson that MS is ashamed to talk about. That being said though, why is RT so lame? Because it basically does what a normal Android or iOS does - run apps, media consumption, web browsing, basic stuff. It is, essentially, a toy and can't run as a full computer. The thing is, those "toy" tablets can be quite fun to play with sometimes and actually can even be handy in a working situation (student, light business, etc). RT tablets are more than enough for a lot of peoples' tablet needs.
With that in mind, this deal? $150 for a basic Surface tablet is not bloody bad. The Windows 8 ecosystem is getting respectable. When you're looking at the $150 price range for "toy" tablets you can either get less than half of an iPad mini or an Android tablet from a no-name Chinese manufacturer that likely isn't Google certified, no USB port, no hdmi out, bare bones. Even the smaller hardware deficient Kindle Fire goes on sale for more than this.
If you can't see this as a good deal, you've let your hatred for MS/Windows 8 go beyond the point of reason. The Surface RT is not a bad tablet, it was just horribly overpriced for the initially app deficient device that it was. At this price, it's a steal, and a pretty damned handy thing to get for $150. I doubt I'm getting one, but... I may get one for my girlfriend for her birthday.
