There's really only two tablet speeds; "smooth" (ipad) and "jaggy" (android).

If amazon makes their tablet "smooth" then that will be an achievement independently and despite of android - not due to a specific android version.

And before the android-fanboys crawl out of the woodwork: The "next version" is always supposed to finally solve the lags, by virtue of some awesome software-fix or raw dual-core power.

However, just today I used an SGS2. The latest "next version", dual-core and all. And guess what: It lagged.

Having used an SGS2 (the Sprint variant) for the past few days, you're crazy. If anything, it's almost a little too fast.

Give it a few weeks. It has an unfortunate tendency to degrade over time.
