Welcome to Samsung and the US Carriers view on what the US Market will buy. They are selling a Galaxy Note 8.0 with 16GB (sorry 10GB) and yet they offer a 32GB in the EU. Yes they both offer microSD, but who cares you can't put apps on the SD cards and the friggin OEM's should know this buy now. The carriers don't care since they want you to use data, data, data and more data and ring up your bill.
Honestly if the 32GB GS4 doesn't arrive I will be forced to get the HTC One which is NOT my device of choice but having real storage is.
