If you really need OpenOffice you... like... run it on a faster computer on which you log in with SSH or whatever. Although unfortunately given the N8x0 only has WiFi it isn't a device which is perfect for travelling being online 24/7.

Symbian has rdesktop and ssh support for ages. The maemo platform also provides different applications than the Symbian platform.

All in all, I agree with the general tendency you outlined, and I will seriously consider to buy a N96 soon (or buy an older model like N82 or N95) because these devices provide more capabilities, and DVB-H is a very nice add-on because some broadcasts are for free.
