To tell you the truth. I still have never seen a need for a faster processor in my N900/maemo5. The same goes for RAM. The only activity that might need faster CPU/more RAM is browsing some heavy-loaded web page (e.g. with Firefox), but at least *I* avoid such pages (even on a PC). Other than that, I don't think I've ever hit the 256MB mark. And I don't need my contact list or xterm or the e-mail client to open in less than 1ms. 1 second is also fine.
