Sure, got it a couple months back.

I've enabled so many functions I had disabled before (ie. multiple Skype and IM accounts, wifi searching, etc), and locked the frequency at 1.1ghz since I no longer have to worry about battery life.

Unfortunately this makes it hard to compare the two, but I can easily make it through a full day now, even with heavy, constant usage. For me, that's enough. The 1320mah would often be dead by 6pm.

When I say heavy, I mean 45 minutes of walking with bluetooth headphones + MP3s or streaming radio via HSPA, maybe 1-2h of web browsing / ssh / gpodder updates, constant openvpn connection for home network, and maybe an hour of dev work. By midnight I'm usually down to two or three bars.

If I disabled everything, I'm sure I could stay on GSM standby for 6-7 days.

I love the way the phone feels in the hand now... nice and chunky. Easy to hold. Can't forget it. Feels.. significant.

The only downside is you lose the lens cap. However, you also lose the shiny silver lens surround, which tended to introduce a blue-ish haze into photos, so pictures look better. It's pretty tough to smudge the lens in its deep well anyway.

Also, no decent carrying cases I've found yet.

Nevertheless, definitely a thumbs up. I could never go back.
