Steve at CarryPad.com just spent some considerable time getting the Asus R2H Ultra Mobile PC lean and mean . He and a friend, Ian Emmett, cleared up 25 processes and 200mb of memory. Steve has documented the process at his blog. The funny thing about this process is that they used the TabletKiosk eo i7210 as a target.
If you have or are getting an Asus R2H, you need to give Steve’s How To article a read. I bet Matt is going to be doing something similar to his R2H.
