I'm starting to have some issues with the iPad that are making me consider returning it.
Recently, I was sitting on my couch with my MBP on in the room, my iPhone in my pocket, and my iPad in hand. The MBP runs Adium, the iPad runs IM+, and the iPhone runs Beejive. I got a gchat from someone, and all 3 devices beeped/buzzed at the same time. That kind of bothered me - I mean, how many different ways do I need to be connected to the internet? I really only need one device that can be mobile, and one device to do more centralized computing (not that a 13" MBP isn't mobile, I just can't pull it out on the metro).
Another time was when I downloaded an album off the iPad. I was trying to get out the house quickly and I usually listen to my music on my iPhone on the go. Then I realized, to get the music to my iPhone, I had to sync the iPad to the MBP, then sync the iPhone to the MBP. It's just a hassle.
The iPad has a beautiful screen, and is nice and portable. And it is super fun to use. But there is absolutely nothing it does that the MBP and iPhone don't do between the two of them.
So my brain is starting to wonder, what else could I do with those $800? I don't even own a high def TV. I could go on a surf vacation with that money. There are just so many other good things to buy or spend money on, and that's making me consider the return.
