I've had a play with the MSI Wind and I must say I'm much happier with the keyboard on my 10v. The feel and response is excellent. The trackpad _is_ a hassle, but there are ways to fix it, although it won't be multitouch unless you physically replace the trackpad unit.
With the 6-cell battery, running Ubuntu 9.04 in a fairly lean manner, I get easily six hours of use and sometimes up to seven. I've no idea what the maximum time on standby is but I've just come back from three days away and it woke up well and still had 20% battery left, and I think it only had 50ish when I closed the lid to go away!
