Hard drive with wireless support

[tieke]

We're going to be away for quite a few weeks over Christmas, so I thought I would copy a bunch of my son's programs and videos across to a HDD to take with us, and then have him watch them on a tablet (Nexus 7 or first-gen iPad).

I've previously used a usb adapter and just plugged a stick into the Nexus 7, but thought it would be cleaner to share the content via wifi. I suspect that external hdds with built-in wifi will be a growing market, but not many are available yet - the seagate goflex freeagent is available but pretty expensive, and Patriot have released a wifi-equipped enclosure that isn't available here yet. Considered getting a router which supports attached storage, but the small ones I have looked at don't have that option, and I remembered that router NAS support was often pretty flaky.

I'm currently considering configuring an old laptop or a raspberry pi to act as a wireless server, but that seems like overkill - does anyone know of a cheap wireless server that might do the job?

cheers,

tieke

EDIT: At the moment I have decided my simplest and quickest option is just to use a laptop and share the files using windows shares via Virtual Router
