Aren't there people blaming Android's perceived laggyness on this?

Many do, but actually the problem is caused by UI using software rendering instead of the GPU. This was only changed in Android 3.0.

Another thing is that many developers do too much in the UI thread instead of doing it in the background or asynchronously.
