McPhee as I said we don't have them as too pricey even for me when we have a perfectly functioning mini Mac and no spare cash. Now my kids do do all you list(and more) however they also had/have laptop time.If I was rich however they'd have an Ipad each because they're far easier to navigate,they can get the apps/books (and god knows what else),are more transportable so we could curl up on the sofa together with them like we do books,are smaller etc,etc
Tonight my dd 7has had a piano lesson,Brownies, was out on her bike and read a book.
Dtwin 2 (8) had a piano lesson and has played out on his bike with friends,finished reading Ruby Redfort.
As well as all that dtwin 2 had an hour on the laptop.He did some work on the website he's made himself(he's Yosemite obsessed so did some research and put some pics on), he looked for some Harry Potter piano music to buy(looked to see if he had enough pocket money),he e-mailed his grandma,looked at some photos she sent of his cousins and then did his homework on it which they're allowed to now and again(he has perfect handwriting and they do written weekly homework before I'm flamed).
If I was rich the above would simply be on an Ipad.I don't see the difference or the problem.My kids have friends that go on v expensive long haul holidays,Legoland,Disney etc,etc.It's life some people are rich and their kids have more,newer things
