No it isn't.
I own a Alienware since 2007.. has XP installed on it, and still works fine, besides battery overheating problems which I will resolve once I buy a new battery pack.
Toshiba is the brand I wouldn't recommend.
You pay premium price for cheap build parts and crappy warranty.
If you're only going to use it for internet and research work, why not buy a cheap netbook?
I recommend Acer 1, MSI Wind series or Asus Eee series.
