Consumers thinking about buying a new computer in 2005 might be better off putting off their purchase until 2006. With few major changes in PC hardware or software due over the next year, the PC of 2005 is likely to look awfully similar to the PC of today.

Big changes aren't due until 2006, when the Longhorn operating system from Microsoft, 64-bit applications, and optical drives based on the Blu-ray Disc and HD-DVD formats will become available to the average user.

Still, that doesn't mean there are no technologies worth looking out for if you do plan to upgrade in 2005."
