Today Mossberg is a lot kinder; writing about the Samsung Q1 Ultra, he says it takes over four minutes to reboot it, the battery lasts about 3 hours, and it costs too much at $800. But his conclusion is: “if you don’t do a lot of document creation, and value small size and weight enough to put up with some hassles, the UMPC is finally an acceptable choice.”

This has to be a huge relief to Paul Otellini. Intel is banking on the UMPC becoming a mainstream device.
