These arguments/debates are pointless because the N900 is actually as capable and more of any apps etc as any other mobile and i would go as far to say that anything is possible on the N900 as it is indeed mostly open and fully programmable and only a matter of time before we have the choice of multiple OS as well as the capability of porting Symbian over to Meamo/Linux.
Remember it is in fact a computer in it's own right.
So basically the N900 has endless capabilities.
Point to the OP for sure is the N900 is a wonderful device and really does not need defending as it will in time shine with glory.
Dedicated users of the N900 know this only too well and as for the rest that doubt ... they will find out lol.
