BTW, regarding my purported weak straw man Dell comparison: I'm not trying to create the ideal comparison, I'm just relating my two choices for corporate laptops at my company - Dell and Apple.
I was kinda disappointed that my new Latitude 630 had such disappointing battery life given I have the bulbous extended battery *and* the bay battery.
Speaking of Dell/MS bashing, I just had the most horrible day of fighting Windows to get my new Windows Mobile 6 phone to (Active) sync via Bluetooth. Half of the websites I found recommended uninstalling the vendor Bluetooth stack and using the MS XP SP2 Bluetooth stack. How any mere mortal could be expected to get this to work is beyond me.
