we have an asus netbook. It is currently hooked up to a 19" monitor and wireless keyboard and mouse. I use it as an upstairs computer, primarily for email, a few forums, and facebook. I recently added a few games for my daughter, as my kids are wanting to play on the computer, but the biggest limitation is no cd drive. Some kids games I own require a disc to be kept in a drive to play. I keep telling myself stop buying these, but I have a few. I is annoyingly slow, but I don't use it for heavy stuff.
Ram, make sure you set the Super Hybrid Engine to performance if you are not on battery power.
