n91 vs w900i

I want a phone that has a musical side to it.
So far I’ve heard stuff about both.

Back and forth, and these phones cost almost the same where I’m buying them. Although I have no idea which one is actually better.

I do have to admit. I find n91s hdd totally impressive, but if the rest of the phone is junk I’ll pass over that one. Like the fastest motor ever built only it has the tendency to blow up every now and again. No thanks.
On the other hand I’ve only had 1 nokia that was around 3310, and now a motorola v975 since last year. Which I dislike btw…

Sony Ericson is a bit of an unknown to me since I’ve never used it. The idea to buy one came from reviews on the n91 that said that this sony ericson was better in some ways.
