That's it, holidays are over and everyone is back to work… today oh surprise, lots of sites announce the soon release of lots of new ultra-mobile computers. 

Interesting enough is the wide selection of operating system proposed (Vista, Windows Mobile, Linux). I wonder which solution will emerge and if the most chosen one will be the most convenient one for frequent travelers.
