Let the hive mind of Engadget get that for you.
"I commonly need to boot a system from an external disc and take a snapshot of the host system. I also then need to burn a copy of the image to a DVD. While I can do it with two separate external devices, and two power supplies, and two I/O cables, it'd be nice to find a small dual-drive enclosure. It would need to have USB, eSATA, and FireWire. Either slim-line or half-height bay for the optical burner would be fine, and space for either a 2.5- or 3.5-inch hard disc. Any ideas?"
What it needs, is a display the size of a folded (in half) regular sheet of paper. ca 10 inches or so.
A built-in mp3-player is nice, but it is also fluff. What I want, and what I think most college/university student want, is a portable library, of the size of one book.
It needs to be rugged enough not to get totally wrecked by bringing to school, in a backpack, full of other heavy stuff.
--The canges I think it needs:--
-Larger display (ca 10 inches)
-No costly exessive features.
-Rugged enough for the real world
-Affordably priced. Why buy one, if you could buy a notebook computer for the same price?
