well its easy for me because i am using a 5800 right now, and this device is phenominal. so an n97 is everything i have, plus camera qwerty and a storage, etc. so its kinda a no brainer for me. i love this 5800 a lot, so n97 can only be better.
my 5800 CPU is adequate for everything i've thrown at it. the n97 has 60mhz more, so that can only be better. that's my thinking anyway. personally i think you're over thinking things to an extent, getting caught up in every minor detail comparison this device vs that feature. just gotta look at the n97 as the best all around package you can get. the ONLY other possibly choice is the omnia, which shouldnt even be a thought cause no 850 3g. otherwise, nothing decent compares. new iphone? weaker camera. touch pro 2? no camera flash.
the choice seems obvious to me. and remember, the n97 CPU is the fastest we've had from nokia to date. lets not forget that, its not like its the same as previous or gone backwards. its still been increased over the 5800! so its still faster than any other nokia before it. just didnt increase as much as the omnia.
