Is there any graphic-accelerated PDF reader for Android? I use Adobe's Reader and ThinkFree Office, but they both are too slow. Any suggestions?
Starting with Android 3.0 (Honeycomb), Google introduced hardware accelerated 2D rendering pipeline. For now it's a tablet-only feature, but hopefully we'll get that in the unified Ice Cream Sandwich platform.

That should be a bit with that slowness issue with PDF readers since they are only able to do software rendering in Gingerbread and older.
