I don't have issues with touchscreens in general, I think they're perfect for my iPod Touch and do eventually plan either an iPhone or an HTC. I just think that (for my purposes) a device as big as a tablet is better served with a touchscreen *and* a physical keyboard. This, of course, matches how I would use the device and isn't for everyone.

The refresh on the Kindle is fairly instantaneous to me, maybe it's faster than the Sony? But I just don't like a backlit screen for reading, so that's a bigger issue than the refresh rate.
