I'm researching which handheld devices would be good for viewing content out of Revit (DWF / PNG / AVI). I'm looking closer at the Nokia 770 Internet tablet.

Does anyone have experience / ideas about DWF viewing on an Internet tablet like this one? or other products I should check out? I'm interested in a smaller / less expensive device versus a full Tablet PC from HP, etc.

Thanks,
