There's a few problems I see right now.
1. All of the x86 tablets that are priced around the same as the RT work nicely if used like you would use a Netbook or ARM tablet: as media devices, and stay away from heavy applications like Photoshop etc. The reviews I've read so far have remarked that they're pretty zippy if you stay mostly in the Modern UI but performance drops in desktop mode. Because of this, I've decided that if I'm going to buy a x86, then I'm going to move up to the $1000+ range get an Ivy Bridge or higher CPU, and use it like a laptop. There comes a point where a tablet crosses that threshold of being to large and unwieldy to use as a handheld touchscreen, and the ones currently available in x86 all appear to have crossed that threshold. Someone remarked that Clover Trail are hot on ARM's heels. Yes they are, BUT they're still not there right now.
2. This leads me to my second conundrum: If and when Clover Trail does totally surpass ARM and allows for RT sized tablets AND zippier performance in desktop mode AND comes in at a price point of around $700+ then I can see that happening in about... 1 year. Leaving me with an RT only one year old that I paid the same for as I could buy a x86 tablet that's evolved past all those shortcomings. That's the risk of being an early adopter. I do NOT want to be like one of those guys who paid $700 for a Blackberry Playbook. I bought my Playbook for $200 just 9 months after it was launched.
That's my honest opinion of the RT. I think Clover Trail chips are going to completely overtake it in about 1 year, along with x86 tablets for the same price range. If that doesn't concern you, then I will say I think the device itself is great. I just think it's only going to remain that way for about a year when compared to its full Windows 8 x86 cousins by then.
