Well I finally got Vista SP1 on my CX210X. I dug around for updated sound drivers and after installing SP1 appeared in Windows Update. The download size was about 66 MB and it took 1hr to install. Yesterday I installed Vista SP1 on my HP tx2051. Performance seems a little faster. The only problem I have found so far is the Sidebar seems to be broken. The Sidebar would get stick when loading during boot. I have disabled it for now.
