Amazon now has the 8 giger via several of their hosted stores. It's currently $89.80 plus about $7 shipping, but this version comes with a nifty little USB reader that takes the microSDHC card directly (w/out need for miniSD or big SD adaptor). And the price is bound to go down, especially with a 12 gig due out in a few months. Maybe skip 8g, hold off for 12? Or, could wait for 8g price reduction, or have 8 gigs NOW! It's here...
