I just updated my Vista Performance Score table with Mendion Scores. This UMPC has so far the record of the slower UMPC running Vista. It's slower than a v7110 with an older version of the VIA processor.
And talking about slow devices, JKonTheRun found another first hand impressions of the Q1 Ultra. This time from a current owner of the Q1p who also found the Ultra to be a slow device.
