i'm a cheep/memory spacious person.. i've got the 16 in mine.. most people are pretty cheep, if you can afford to try it and it works fill us in! otherwise just take it back and yell at them untill they give you your money back.
It works!! I bought a newer 64GB Micro SDcard. I then downloaded the free home version of Partition Wizard to my windows-7 PC. I stuck my new micro into a SD adapter and placed it into my PC. I then used Partition Magic to format it into FAT32. Once finished I placed it into my Acer tablet and it works perfectly showing all of the free space. I loaded game roms and music videos and they all work perfect!!
Just picked up an A100 and SanDisk microSDXC 64GB, Class 10. Formatted FAT32 via Mac OS X 10.82, single partition. Mounts and recognized immediately in the A100 with 59.45GB capacity.
