I'll admit, I'm in the percentage of people who have an iPad.
I love it. It's a great web surfing device, email checker and I like my apps too. One thing I hate about the iPad is the lack of sleep that you get with it.
I've tried to resist the urge to grab the iPad in bed and read a book or check in Facebook/email/whatever before crashing out but I can't always.
One thing I guarantee is that the tablet will keep you up at night. Which is why adding them to hotel rooms is great for public relations, but no good for your zzzzzzz's.
