Unfortunately, word has it that the U150 may not make use of Windows 7's multitouch functionality. The device supposedly uses a resistive instead of a capacitive touchscreen. SlashGear notes that the decision is probably an attempt to keep costs down. While that is still a year away, MSI recently announced that it would introduce an AMD-based version of their Wind U200, the Wind U210.
The two disclosed U210 sub-models will bear similar specifications. The U210-002 sports a 12.1" display, an AMD Athlon Neo MV-40 1.6GHz, 1GB of RAM, an ATI Mobility Radeon X1250, a 160GB HDD, and Windows XP. The U210-010 kicks it up a notch with 2GB of RAM, a 250GB HDD, and Vista. The former will ship for about $570, and the latter $642.
