Same here. I've never owned a single tablet, but I'd likely get one if it was at least 128GB.
Even if they discontinue 16GB model. I don't see why they would do that. Mass market customers barely criticize lack of storage or exclusion of expandable memory via micro sd cards. The 128 model would cost $700-800 plus tax just for wifi version. Gets rather expensive and into the realm of macbook air.
OT: The desktop/laptop market is declining though as lot of people are moving towards tablets. So there is lot of money to be made for those who get it right like Apple.
