Head on over to XDA Developers to get ICS on Kindle Fire with full hardware acceleration and only a few bugs.
I’m not sure if it is worth buying a brand new Kindle if something great is coming around the corner (Google Tablet) but putting ICS on one you own already is easy and quick.
I know I am loving my Kindle more every day.
Two ROMS to try:
