I would like to see a list of things you cannot do with iPad for a REGULAR user.
Regular user is someone who checks email, surf the net, Facebook, Flickr, etc.
I am no different than a regular user except I do not have an active Facebook and Flickr account 🙂
I am curious to see since I am planing to buy the iPad2 and use it with my Apple Wireless keyboard at work.
Maybe not a good idea????
The most obvious thing you cannot do with an iPad is, it doesn't work with flash. So if any of the sites you visit regularly uses flash, they won't work on the iPad.
You also can't upload files from the iPad to websites. Like if I had a picture on my iPad that I wanted to include in this post here, there's no way to do that. I'd have to upload the picture to a photo-sharing site on the web first, then include a link to that site in my post.
Other than that, I can't think of anything the iPad can't do -- oh, printing is still not implemented fully, but that should be coming in a firmware update at some point down the line.
Mostly, an iPad can do most things a computer can do, but often not as easily. For instance, you can type up a document in Pages or one of the other Office-compatible word processing apps, but if you need specific formatting, it's a pain, and in any case, it might not convert properly when you transfer the file to a computer. Getting files into and out of the iPad isn't as straightforward as doing it with a laptop. I have to juggle two or three apps to accomplish this, and I don't think a "regular" user could remember all the steps.
Upshot is, I ended up getting a MacBook Air for the office. The iPad is great for entertainment (reading, videos, games), and for getting the odd work done while on the go. But if I'm doing enough typing to need the bluetooth keyboard, then what I really need is a "real" laptop, not the iPad.
