I have an iMac and an iPhone and adore both, I am a total Mac geek. Because people know I love Mac stuff I keep getting asked whether I'm getting an iPad but (money aside!) I'm not sure what I'd do with it! I use my Mac for most things at home and the phone for if I'm in another room or out and about. What can the iPad do that I can't do with these? The only time I could see it being useful (and justifying the cost) would be showing work to clients (not even sure I could do that as I don't know if you can run the software I'd need on it) but that isn't something I need to do that often. That said I could totally be persuaded to save up for one if there's loads more it does that I'm not aware of but at the moment it just seems like a halfway house between the 2 things I've already got.
On a separate note, I am considering buying DH a Kindle for Xmas - we are both avid book readers and while we love 'real' books we are running out of space! DH in particular gets through loads of book as he commutes, and once they're done with we never know what to do with them. It seems that a Kindle would be a good investment, even if he just used it for travelling but it's a lot of money to spend and I'm not sure whether he'd need the 3G one which would make it even pricier.
Any thoughts from gadget-loving MNers?
