im planning to get this phone as bday gift for myself. lol but i'm having some questions in mind. like (1) what comes after this n900? Nokia is known for its fast pace in releasing phones.. like n97, then suddenly came n97 mini followed immediately by n900.. will it be followed by another phone too quickly that i'd regret buying it? (2) since it's a web browser and all, is there some kind of virus scanner for it? (3) if there'd be a maemo 6, can i also use it for the n900? and the last one (4) why is the price dropping quickly? last week, i looked it up on the nokia site and it's $649.. now it's only $569.. what's wrong with it that it suddenly dropped price? thanks!
