@skywys19, do have a loot at Asus P320. I would highly recommend it over your Asus P527. Few people have that, and its a rather old model, and its a little pricey IMO even at 999. U might as well go for P320

specs wise they are identical. P320 is newer though, lighter, and without (for me) a redundant keypad. the T9 keypad u can easily use a virtual keypad, so its useless IMO. it comes down to which design u prefer. The P320 is decidedly nicer aesthetically, as well as smaller. u decide

i dun understand your question. Both devices have exactly the same rom and ram, with expandable storage card slot

depends, cuz the program memory is affected by what u install in the pda memory, and ram affected by what is running in the background. bottomlime, ALL pdas will have less ROM and RAM than stated by default, due to usage of ROM and RAM by the operating system itself, plus whatever the operating system comes with. The best way to free up as much as possible will be to flash a cooked "clean" (empty) rom/firmware. All pdas will be like this, not just p320. hope that answers your question.

@ayampercik, like skywys19, i would recommend looking at both the Asus P320 and Asus P527, both fit your budget plus GPS( so a bonus). Fit your budget brand new.
