You have absolutely no idea what you are talking about, and are just ranting through your Apple hatred glasses. I have an iPad and I get real work done on it every day. For example just today, I gave a 50 page presentation using my iPad. And a few weeks ago, I was giving a presentation to about 100 people. and right before I went on, I was still editing my presentation, right on my iPad.
I am also able to get my work email and calendar, so, I have the ability to do most communication tasks I would do on my desktop. Plus, in a pinch, I can turn on VPN in to the work network, and run VNC, and do some tasks there.
Also, since the iPad is so small I take it everywhere, and I have the 3G model, so I can almost do all of my work from anywhere at anytime. Recently there was an issue with one of the applications I manage, and I wasn't home, and all I had to do was take out my iPad, connect, and I was able to fix the issue with just the iPad.
