Well, I love eating my words, so here we go.
Today, I jumped to 2.2. As for the lag in the browser, I noticed it as well. I also downloaded the full flash thing for shits and grins (have no real use for it on my phone), and I noticed pages scrolling kinda chunky and whatnot, and it was because it was loading ALL the flash objects. Go into the stock browser and under thr settings, there should be something pertaining to that. Just check it to 'On Demand' so it doesn't load anything unless you tell it to otherwise.
