Well I went and bought the O2 Atom today. I looked seriously at getting the Dopod 900 a.k.a. O2 XDA Exec, Qtek 9000 but couldn't justify fitting something that big in my pocket without getting too much attention ;-) I had read that the Dopod 838 was disappointing and overpriced for what if offered. That left the O2 Atom and Dopod 818 Pro. The 818 Pro has both wireless 'b' and 'g' which on paper looks great but in practice is of little advantage to me unless I intend to transfer files of several hundred megabytes in size. The FM radio on the Atom is personally speaking useless especially here in HK. The 818 Pro is cheaper but what swung it for me was O2's ROM updates available from their website, the brand name's higher resale value and the longer battery life. Fortress's Atoms are already running the January ROM update.
