Thanks, I just ordered one. I have a G2 now, but I've had everything from the G1 to the CLIQ to the MyTouch Slide and it's been really confusing figuring out what microSD will work and what won't.
I don't know what the technical issues are, but I can't wait until you can match the storage of an iPod. I love doubleTwist, and if I could have it just sync everything automatically it would be so ideal, but my collection is way too big, but it fits on the biggest iPod so I end up still carrying both.
