“Why would they want to be working on a computer when there is a bright sunshiney day to play in?”
Actually this is a good thing in that it gives me yet another reason to pick up a Kindle as well as an iPad. First off, I’ll be a lot less nervous about a <$150 Kindle at the beach instead of a $500-$800 iPad. Second, the Kindle is better for bright conditions anyhow. Third...this overheating issue! Perfect!
(Yes I do active stuff outdoors too - but I also enjoy reading there!)
I'd be less nervous about a $4.95 paperback.
If you enjoy reading let me suggest a very inexpensive and enjoyable device that will let you read everywhere without regard to overheating or someone stealing your elctronic device.
It's called a book. Works every time and never overheats (Well I guess it does overheat at 451 deg F)
