I don't really see the fact that the SD card is under the battery as detrimental. Now, if we were using a windows phone, it absolutely would be, for one reason. Transferring large amounts of data through the phone to the SD card (via usb cable) is PAINFUL in windows. You MIGHT get 3megs a second transfer on a class 6 card. As opposed to pulling out the card and getting 15megs a second using a USB microsd reader.

I've tested the data transfer rates on a co-workers incredible, and it was actually faster to do it through the phone then it was with the microsd card reader (15megs per second)... And that was on a class 2 card. I was getting 12 megs per second via a usb microsd reader.

Assuming the evo has similiar rates, I don't think it's going to be an issue. I'll put my 16 gig class 6 in there, and probably won't take it out till I replace the phone.
