The N900 is almost 2 years since launching. Do you seriously think a 2-year old ARM can support tomorrow's newer application requirements?

Just fill up your N900 32Gb with all the available (and useful) apps today and enjoy it. It's still a great multitasking device and has some nice functionality. Use it as a secondary mobile laptop or mutimedia device, or whatever.

Unless you just need to/must have the latest gadgets.
