Wife is running it on her laptop - Dell Core 2 Duo, 1 gb ram
She loves it, so far, but she has had to grapple with a few networking issues, also some software incompatabilities (her TrendMicro won't work on it, so she downloaded AVG for the moment) She's running MSOffice 2007, ie8beta, windows live, paint.net, Palm desktop, Firstclass email, Adobe Acrobat 9 Pro
It doesn't like her Palm tether, so when our ISP died, she couldn't even go wireless, so that wasn't cool...
So far, it's been workable.
People I've talked with are liking it... but I'm in no rush to change my MediaStation over... things work just fine the way they are...
