The UMPC market has not exactly been huge so far, but the largest contender in the market, and the one with 65% share, is the Samsung Q1.
Samsung is proving its commitment to the handy platform with a new Q1 model. The third generation Q1 device is due to come out sometime early next year. No specs are available as of yet, but there is a strong indication that it could be Atom based.
Samsung has continued to improve its UMPC offering, and no doubt the next model will continue to be a strong entry into the market.
