Surface RT a little pokey... any hope for updates? Or hardware limitation?

First off, I absolutely love my Surface RT. I switched from an iPad 3/iPhone 5 to a Surface/Lumia 920 combo and I'm very happy with it.

The whole "Windows 8 vs. Windows RT" thing didn't bother me, because coming from iPad I was well aware of the "if it's not in the app store, you can't install it" thing.

My biggest concern is the sluggishness and the bugginess. Using the Xbox Music app is at times unbearably slow, and I can't even wrap my head around how bad the People Hub is, especially when compared to the great experience for both of those services on WP8.

Any hope for this stuff to get fixed in software updates, or are these the kinds of issues that require faster hardware/more RAM/etc.?
