Eldar does a k750i vs. n90 matchup
Of course I'm a Nokia whore, but the N90 is better imo on both distance and close up.
Unfortunately, the thing is as big and heavy as my Jetta and has no silent "vibrate "function. As I like to carry phones in my shirt pocket and have no affinity for "crazy frog" in business meetings, I think I'll be skipping the N90.
