No app ATM, but it's a PITA if you try and edit something...
Mostly I do what I'm doing ATM, tether the laptop to it.
Interestingly Dave Blears who owns/runs the Aussie Land Rover forum is a computer shop dude and doesn't really like Tapatalk, reckons it often causes problems with forum software, he tends to prefer Forum Runner but it depends on the forum too and who they've optimised it for.
I used to think tablets were just a flash in the pan phenomenon too, then when I did my course last year half the girls were using iPads and if you can cope with a touch screen were brilliant in that situation.
One even recorded all the lectures with it then transcribed later. All their course notes and manuals were available easily.
I ended up taking the lappy in after the first week but still wrote everything down with a pencil and pad.
The wi-fi range of the iPad is pretty poor but there are merits to the bloody things too, so much so I think a Windows or Android tablet would suit me better on the road than lugging around this big old lappy.
Bloody technology, the bastards end up snaring you eventually. Resistance is futile....
