On balance, the Nokia E72 is a very appealing phone - being an update of the E71 it packs in a plethora of enhancements and improvements of most core features, and if you can't decide which one to choose, definitely go for the E72, unless you're in the market for a cheaper solution.
Props to Al Pavangkanan for bringing this to my attention; according to him the brown model looks hot -- not sure if I agree, but there's certainly nothing wrong with choice!
Possibly missing from this killer Eseries device are (1) Carl Zeiss optics and (2) an on-board podcasting client... Can anyone confirm or deny this?
