Folks... I'm waiting to pick up a new Nexus 7 when/if they come to Canada or the next time I'm through the USA, but that's for 'daddy's use.' Having two small kids (5 and 4) I've thought I'd like to hang a couple of tablets from the seatback for long car trips. It would make far more sense than the CD player that they have now.

They'd basically only be used to watch movies or play basic kids games. We don't need a lot of features (aside from durability, which may be a nice plus, but depending on how inexpensive they are, not worth paying for.) In other words, sure, I can buy them iPad minis, but I consider that a Rolex when really, all I need for them are cheap Timex's.

Any thoughts/sources/recommendations for what would be considered, essentially, 'disposable' technology?
