New at Eastgate (and cool!), we've got a shipment from England of NeoCase laptop sleeves. They're high-density, edge-reinforced Neoprene sheaths, tailored to fit each model of iBook and PowerBook computer.
A nice detail of these cases is that the zippers are protected by flanges, so they never touch your computer. The case has retractable handles, so you can carry it comfortably yet fold the handles away in your briefcase or daypack.
Tinderbox can't help you take notes if your notebook is back at home because you just didn't want to lug your big laptop case. Be prepared.
And it's just $29.95.
