I've been using my Samsung Q1 UMPC for several months now and find it to be an extremely valuable part of my gear bag. I particularly like it for its mobile multimedia functions when traveling or commuting. I have not had the opportunity to check out any other UMPC device since you can't find any but the Samsung Q1 in retail stores. CTitanic is a TabletKiosk eo V7110 UMPC owner and recently picked up a Q1 so he posted a good comparison review that shows the contrast between the devices and their intended purposes. He agrees that the Q1 is a great multimedia device, but states that the eo V7110 is a better work machine. The eo V7110 excels in navigation controls and available hard drive options and looks to have an advantage in screen sensitivity. I hope to try out other UMPC models in the future and personally look forward to the next generation Samsung Q1.
I understand that TabletKiosk is holding road shows in Orlando (November 9th) and Houston (November 30th) and encourage you to attend one of the events if you are in the area so you can get your hands on a new UMPC and try one out yourselves.
