Bought the 16 gig 2GB 1.83ghz ZenF2 recently.
I watch movies, shoot video and take pictures, listen to music, text, surf the web, scan receipts, keep lists and personal records, on and on with no trouble what-so-ever...
Sometimes I make or receive calls also (nice forgotten feature of these devices)
However I do spend a bit of time moving downloads and apps to the SD card which does help with device memory for overhead.
That being said I have been thinking of trading off my 16 gig ZF2 for the high spec'd 64 gig version.
Knowing what I know now I should have spent the extra $100.00 bucks.
