I have lap tops(Acer, HP and a no name ), desk top, Compaq 1850R servers , EePC and my partner has her Ipad. Her kids have Iphones and Ipads as well. But when we are away, the Galaxy TAB 10.1 is what goes with me.
The laptops are too fragile - sick of replacing hard drives and cracked screens, the EePc does about every 2nd trip as it is a tough little machine, but the missus is the one that uses it for longish emails.
The others are not travel friendly in any way.
Apple stuff is for consuming internet gunk, you need to get to MacBooks before creating ( editing photos and videos, decent length emails etc) stuff is feasible for me.
Touch screen keyboards are just way too painful to use. But the Galaxy TAB with a roll up keyboard, tiny Bluetooth mouse and a couple of 8Gb memory cards plus a 1Tb portable drive works a treat.
