Do I understand correctly that it has only 256Mb RAM ? That's only double than N810 which is almost 3 years older.
How much can you achieve with 256Mb when you have a full Firefox browser.
I'm very afraid the history is going to repeat itself (N770, G1 Android, etc): we're going to ran out of RAM and next version will have more RAM out of the factory.
Why can't they put 1Gb RAM from start ?! It's not that expensive.
