My wife wants me to look at an all-in-one toy to keep my preschooler daughter entertained for a long trip we'll be taking next summer. She's interested in a LeapPad 2, which will be available for $35 on a Black Friday doorbuster special, but the apps can be so expensive ($25 for a cartridge) versus what's on the iOS and Android stores.
SWMBO's got a 2012 Nexus 7 now and we'll probably be getting her a Nexus 5 next month once our cell contract expires. I'd rather let kiddo play with the phone (it'll have a protective case) but SWMBO's worried about my daughter getting used to that idea and wanting it frequently. I don't have my own tablet, being content with a Kindle 3 and my dearly-departed Cr-48, but I do have an older 11.6" laptop that dual-boots Lubuntu and Windows 7, and the kid's comfortable with a touchpad, keyboard, and touchscreen. Between the two of us we have a large Steam library; the age-appropriate stuff is from the Popcap bundle and some of the Humble Indie Bundles.
The trip itself will be 2-3 hours on an airliner followed by ~a week of traveling around California followed by a return plane trip, most likely in economy class. My daughter's pre-literate, can spell a few words, knows her letters & numbers, loves drawing (Tuxpaint is a favorite), is big into imaginary play.
Basically I'm a bit overwhelmed by choice at this point and would like help narrowing down what I should do.
 she's not as good at telling our daughter "no" as I am.
