What's your basis for comparison? Your extensive experience with OS2008 on OMAP2 devices? I've used all released versions of Maemo very extensively, and none of the 770 experiences (with OS2006, OS2007HE, or OS2008HE) stack up against the OMAP2 devices.
The N800 has twice the built-in storage
twice the memory, twice the speed
twice the speakers,
many times more removable storage,
a better screen
and a kickstand.
It's a vastly superior device.
