I sell laptops, parts and service for a living. Nearly all of the big manufacturers are offering a free Windows 7 upgrade with a Vista computer purchase. The only version of Vista that does not qualify for the upgrade is Vista Home Basic. Your average user will not gain much between 32 and 64 bit operating systems. The main differences between the two are more limited memory of 3GB with 32 and possible software compatibility issues with 64, which support 4-8GB depending on the unit. Windows XP is still available on many laptops that we sell and includes Vista Business and 7 upgrade, so you are essentially getting 3 operating systems. However only one OS may bee installed at time.
Tom, if you are looking for a laptop I can hook you up with one or at least point you in the right direction. I also have a couple screaming side deals on new XP Desktops. The desktops are custom built ones that I am selling on the side. Desktops are $350 complete with Samsung 19" LCD monitor, keyboard, and mouse.
New Notebooks start at $479. XP Notebooks start at $579.
What's wrong with your laptop? Maybe we can fix it. What brand is it? We are a premier service provider for Toshiba, Lenovo, IBM, Fujitsu, and HP/ Compaq Business units. Let me know if I can help.
