I had an irritating problem with W7 x86 pro on an ACER 1GB A520 Netbook -- whenever I type the cursor sometimes randomly jumps ANYWHERE on the screen making inputting things like a Word document impossible as I overwrite parts of the text and the document just comes out like garbage.
I know its something to do with the screen / chip set drivers but I couldn't find any solution to this problem WHICH IS A SHOW STOPPER.
I've had a similar problem to this on another computer in the past and I can assure you it's REALLY ANNOYING too.
Anyway I installed W2K3 SERVER on it -- I modified the W2K3 server to operate as a Workstation OS and it goes PERFECTLY -- not denigrating W7 but W2K3 was designed as a SUPERFAST OS.

Office works perfectly without garbling the input any more and I've got Games on it as well as well as Photoshop CS5. (not the rest of the CS5 suite -- just Photoshop).
Maybe I'm bonkers but I'm actually satisfied with the performance too -- the Netbook has the newer AMD processor so it's more than sufficient for a SINGLE user.
