Comment Comparing with iPhone (Score 1) 484
I didn't find any good comparison, so I wrote a simple comparison table: http://markogronroos.blogspot.com/2009/08/n900-vs-iphone.html
Looks like N900 wins iPhone easily on hardware specs, though iPhone does have a few advantages (slimmer, possibly better touchscreen). N900 wins on some very important software issues as well, such as Flash and Skype, though iPhone does have much more software (commercial), at least until old maemo software works in Maemo 5 (if it doesn't directly).
My guess is that iPhone will win in usability and responsiveness, but that's just a guess, Nokia has a chance to surprise us there. I'll be waiting for N900 eagerly and will possibly buy it at some point, although my E90 is just 2 years old and has much much better keyboard than even N900...
Oh, I really hate the three-row keyboard concept in N810, N97 and now N900. I've actually had real nightmares about using Nokia's bluetooth keyboard, which also has the numbers and qwerty row combined. That's definitely the worst thing in N900.
