Having chatted with daisy_knotwise
on the subject, it turned out that the thing she wanted most for her birthday (that was actually obtainable) was a lightweight laptop suitable for reading e-mail, web browsing, and letting little girls do their homework on under supervision. So after lunch today, we headed over to Sam's Club and I showed her the tiny HP laptop there with the 13 inch screen, 32 GB of flash storage, and a dual core processor.
It came home with us.
Gretchen is very happy.
Katie is jealous. :)
