On Monday Samsung announced full details of the reduced price and upgraded performance for the US release of its Q1 Ultra UMPC (ultramobile PC). Today a spokeswoman for Samsung's UK PR company told PC Advisor: "Unfortunately the Q1 Ultra's [UK] release has been delayed until June."

The spokeswoman also told PC Advisor that UK pricing for the Samsung Q1 Ultra is yet to be confirmed. At the time of writing no UK details are available on the Samsung website.

Samsung first exhibited the Q1 Ultra in March at the Cebit tradeshow in Germany. On Monday in New York, Samsung released full details of US pricing and specification for the Q1 Ultra.

In the US Samsung will sell four models of the Q1 Ultra for a range of $799 to $1,499, significantly below the price range of $1,300 to $2,000 for the original Q1 product. You can pick up a Samsung Q1 for around £700 in the UK.

The lower price helps Samsung to pitch the Q1 Ultra UMPC as a lightweight companion device to a user's desktop or notebook PC, as opposed to a stand-alone computer. Samsung hopes it could help it win market share from competitors Sony and OQO.

The Samsung Q1 Ultra has the same size 7in display as its predecessor, the Q1, but adds a split qwerty keypad for thumb-texting, offering similar operation to RiM's BlackBerry or Palm's Treo smartphones. The Q1 Ultra also has 802.11 wireless networking and optional HSDPA (high speed downlink packet access) connectivity. Samsung was careful to avoid comparing the Q1 Ultra to a smartphone.

"A smartphone will always be the ideal platform to be used as a phone. I would never suggest the UMPC as a phone replacement; it's just too big to fit in your pocket," said Bret Berg, senior Samsung product marketing manager for mobile computing.
