a netbook keyboard is cumbersome. I easily understand how you can hate laptops - I have trouble with small keys and layouts below 15" laptops with no keypad or giant laptops, 17" and bigger.
plus you often have lousy sound, and unreliable parts such as the power jack and the optical drive.
a modern, high quality and big laptop is a pleasant computer to use (thanks to gigs of rams, modern hard drive, and less bad display/sound than before) but not all laptops are so.
I have to reinstall software on my netbook by the way (odd and nice little machine with a rare x86 cpu, slower, cheaper and lower power than VIA and Atom), now that there are newer distro releases such as Linux Mint LXDE Edition and Ubuntu 10.10 ; but a third of the keyboard (eee PC clone) doesn't register keys. so I have to dismount it while fearing to break it down more, or have to buy a USB keyboard. (never, ever bought a keyboard)
Boring!
I would like an iPad, for the same reason a big laptop is useful : to fuck around on the web and videos. Desktop PC will always have a superior keyboard and superior display (not glossy TN) if you really want to get "Serious"!
plus a superior sound system : a 250€ desktop with 250€ of audio gear is fun and costs the same as a laptop or ipad.
well.. actually I'm using some family laptop than never leaves the house, it's a giant one (18.4"). it's very good for fucking around, an ipad would be more portable but more limited (it would be worse for typing into the forum, but may be better for some casual video). a netbook would be inferior to both for fucking around. but would be superior for some travelling usage.. which you might not need.
to use a netbook, you need to be away from a public/work/personal PC, but not away from a usable power outlet for more than two hours (as the battery life is low).
and a netbook can do everything, but are the most fragile kind of laptops.
they suck, as they can easily be that one computer you never use. most people who run them either use them as their only laptop, or as their only computer (in which case I would argue for them).
