If you're planning on buying a laptop with Windows Vista Premium next year, you're going to have to pay a little extra for something you may not need. That something: a hybrid hard drive.
Starting June 1 2007, Microsoft is making hybrid hard drive mandatory for laptops to contain the "Vista Premium" Logo. For hard drive makers that don't currently have hybrid drives, Microsoft will help them get set up with a partner to introduce one for use in laptops. So far Seagate and Samsung are the only two manufacturers to make hybrid drives.
If you've already purchased a laptop that's capable of running Vista, there should probably be no problem in buying a copy of the new OS and upgrading your machine.
