Hi Ruper,
one of my colleague, Keith (a new media specialist) is using MSI Wind U100. He is also a Win7 fan.
WHen Win7 was available, he loaded up. To his surprise, Win7 runs faster than the XP that was shipped. He loaded Photoshop right in front of me and i thought it loaded faster than on XP.
I know most people out there had feedbacks that Vista is very slow and resource hungry. With the additional Vista SP1, and the upcoming Vista SP2, you will notice performance and stability improvements.
But Win7 changes the cards around, its truly performant and locally in Singapore, we've tested with the following models; Asus EeeBox, Asus EeePC, MSI Wind U100, Lenovo S10, HP Mini 100 (I hope i got this model right). All runs fast even with 1GB of ram.
However, certain model of the Netbooks has a small problem. Win7 didn't readily recognize the device drivers and we had to load them ourselves using the Vista drivers (if a Win7 one is not available from the manufacturer). We'll fix this when we release Win7 over next few months as more drivers gets written for Win7.
Oops. Short question, long answer. In short, it'll work fast !!! Try it.
