That's one large laptop you have there!
Windows 7 home comes in 4 variants-
1. Starter edition. The bread and butter edition, meant to be a trial pack.
2. Basic. As the name suggests, it offers only the basic functionalities, and misses out on many features - read multimedia.
3. Premium (I have premium too) The best version, offering VFM
, and the software features and multimedia capabilities that one needs, and even more.
4. Ultimate - All the features MS can offer on Win7. Read - Too many features, too high a price.
For exact specifications and such, feel free to visit the Microsoft website.
Note - If you are new to Win 7 & Don't know all the capabilities, go to the control panel and you will find "Find out what's new in Windows 7"
