Dell has a toll free line in most countries. Take advantage of it. As to the iPaq, I've never seen it do that. Maybe I missed it... But from memory you don't want those models since the Wifi cards (and others) don't work.
Can you switch to landscape mode on the IPAQ H2210/H2215 and the Dell X30? Are there any limitations?
I know on the Tungsten T3, it just takes the touch of a button so I was curious about these models as well.
