Vinh - most of your issues relate to closed source applications, and these applications will not be improved with significant new features due to (according to Nokia) licencing issues. I don't want to disappoint you, but you won't get significantly better Web App 1.0 support (AJAX etc.) nor will you ever get Flash 9 on the 770 (I'm not even sure the 770 has the CPU/memory to play Flash videos acceptably).

Bug fixes are pretty much all we can hope for - and there are plenty of those out there to keep Nokia busy before they get to adding any new features. Nokia could go bankrupt tomorrow yet the 770 will continue to receive application software updates - the 770 is not dependent on Nokia, except for firmware updates.

As for the PageStream comparison - that's all well and good but take a look at Windows Mobile devices for a modern day comparison. Want the latest version of Windows Mobile - guess what you do? That's right, buy a new device! Although some manufacturers may offer chargeable upgrades of the latest OS for existing devices, this is the exception than the rule.

Oh, and the 770 is nothing like a 350Mhz (Pentium II?) with 256MB RAM!
