S60 (Symbian)

I have owned Nokia's products forever and have a great respect and liking for them. I used to own a Nokia 6822, and it was great. I have had little experience with any more recent models because my 6822 lasted so long and did so well (they are almost indestructable). I would ALSO be interested in hearing more info about ALL the phones you have mentioned "Marlon," and any Other PDA-style (or keyboard equipt) Nokia phones.
This isn't ENTIRELY related to your question, BUT I felt I should warn everyone... I recently purchased a Samsung BlackJack for it's features and Keyboard. Despite all the research I did, I am regretting moving away from the "Nokia" brand, because this phone SUCKS. Overall the phone isn't Entirely Horrible, BUT Windows Mobile ("Windows:" DUH) is very Glitchy. Matter of fact, it was problematic straight out of the box!!! I only payed Fifty dollars for the BlackJack ("LetsTalk.com"), so I'll call it a learning experience... Thanks!
