Not sure if you are still deciding June2009 but if you are and your budget can stretch then I definitely recommend the iPad.
It is without a doubt the gadget of the year.
It is one of those devices where you truly will not appreciate it until you own one for a few days.
I have the 16GB model and have filled only half of it. I have lots of films, music, apps & books. I took it on a business trip to London the other week instead of my laptop. Made life so much easier.
The beauty of it is the fact its instant on, light (compared to a laptop) and battery life is about 8 hours use. This means I only need to charge it every couple of days.
My friend warned me that as soon as I get it, i'll lose it and he was right. Despite initial resistance from the family over the price, the GF and the kids all love it and most of the time I get it back when its low battery.
It's SO easy to use that our 3yr uses it regularly. He navigates the menus, chooses the games he wants. It's great! Unlike a PC where he's constantly demanding this or that.
Finally Angry Birds HD is a must have app. Arguably worth the price of the iPad on its own!
