OK, so I have to admit: there are indeed some (wi-fi) connectivity issues with the iPad. For one thing, it sometimes just goes offline. A message will pop up which claims your password for your router is wrong.
Worse, it's often not good for videos. For instance, I've almost given up on watching Apple's own videos on it, which really is a bit embarrassing for Apple. They download like a crippled snail.
And until iOS4, you can't change to another app and let it download in peace, because all activity stops in an app when you go to another one.
Worse, you can't even change to another page in Safari and come back to the video later, because for some reason (unlike Safari on Mac) Safari re-loads every page each time you select that page, which means that the video starts downloading all over again! Gawd.
And it's not my Net connection's fault, because on my Mac, they download like horny lightning.
Well, perhaps you just don't need/want one, and that's fine. Anyway, don't mind me, this does not bother me often, and all these things are just the normal little weaknesses you find in anything complex product. I'd say that especially for a 1.0 product, the iPad is enormously well done. I really like it.
