I have both an iPad and a netbook, and the netbook is strictly more useful than the iPad. If I go out with the iPad invariably I hit a wall. No SD card slot. No USB. The keyboard is hunt-and-peck.
The iPad doesn't remember my Facebook password, so when I want to check Facebook I must reach for the netbook. A small thing you say -- but operating systems are collections of hundreds of small things, and new operating systems like the one in the iPad don't have them and old ones like XP do.
I had pictures in my camera the other day. No way to get them up to Flickr through the iPad. If I had had the netbook with me, no problem. (I used my Droid instead.)
The netbook has a real keyboard. I'm writing this blog post on it. It's taken a couple of minutes so far. I'd still be on paragraph 2 if I had used the iPad. And I'd be entering it on one of my WordPress blogs because my customized content tools don't and will never run on Apple's new platform. (Unless they change their mind.)
There's an awful glitch in the way the clipboard works on the iPad. Try to put the cursor on a mis-spelling. It always selects the whole word. I've gotten in the habit of retyping the word when there's a one character spelling error. These little things are of course little, but they mount up.
I think the tech industry should give up the belief that netbooks are a temporary thing and fully embrace them and make the work better and better. Ultimately the user is always right, and ultimately always gets what they want.
Apple has a long way to go before the iPad is a useful tool. Lots of little things to fix and tweak, and a philosophy that's going to keep the really innovative stuff flowing elsewhere (where -- not determined yet).
I hear Asus is coming out with an Android netbook-style tablet in June. Sign me up. I bet it's a nice computer. Android of course is just as immature as the iPad. I'd really like to see a Windows XP tablet made by Asus. That would sell pretty well, imho.
