Lack of built-in memory? I don't see the Touch Pro2 lacking at all in that respect. It has plenty of RAM, 512 megs of flash ROM and an SDHC microSD card slot for potentially many gigs more storage. I really don't know why T-Mobile never updated the Wing until now-- it's 2 generations old and the TP2 isn't even in the same league. No frequent out of memory errors and it has lots of storage and a much faster CPU.
