Web browsing performance: With the releases of Chrome and Safari on the Windows platform, nothing much else can compete close to them.

Battery life time per charge: The U1010 has an extended battery which will last me 5h and 20 minutes of DivX playback via a wi-fi connection (shared from a home system. My own benchmark). It can go into standby for 5 days, and lasts me 1.5 days of (my) typical usage (not constant, non-stop usage).

Podcasts: Yes, the N810 wins here. I used to pair my E71 to the N810 for podcasts. But for the trip, I'll be in a different country, data plan will be expensive.
