What's wrong with a mouse? I see no benefit in a controller.
In the future the mouse will become redundant as touch screen becomes widespread (see Apple's iPad). A controller seems like a gimmick and is not the future of online poker, in my opinion.
Not to change the subject, but... The iPad is a joke and is going to fail miserably. Apple is making this thing out to be groundbreaking technology, but it isn't in any way...
Touchscreens/Tablets have been around for years, but they haven't been a huge success because they don't serve the proper purpose for everyday use. They are mainly just used in hospitals and the military uses some as well.
Also, Apple is making it a completely closed OS. Meaning that they need to approve of ANY software that you run on it. So you can't just go to
www.anysite.com and download a program that you might think would be cool, unless Apple said it was ok. This is forcing people to go through Apple for absolutely everything. It's one thing to do this with a cell phone, but for a whole computer??? Come on. I think it's funny that all of your Apple fanboys will go on and on about how Microsoft was a monopoly, but the evidence for their own beloved being even worse is right in front of their faces.
