I have been anxiously awaiting the release of the very portable Asus eee line of computers. According to rumors the wait might be over this Fall. In the mean time you can view a few details at the official eee web site.
Another rumor that I have found is that the price is continuing to creep closer to $300. I think that the sweet spot for the pricing of a computer like this is about $200 to $250. I hope Asus does not continue to kill this computer market segment by over pricing.
