Modern computer specifications are confusing. Back in the day it was extremely linear. Oh, your computer is 233 MHz, this new one is 300 MHz, or 450 MHz, or 1 GHz. It was like owning a Supersoaker 2000, and wanting the newly released 3000.
Now, I have no idea what I even own. As someone else said, it's a dual-core something or other. There's no upgrade path, or direction for consumers to follow. If you walk into a store, it's quite confusing, and it's difficult to make sense of all the recent hardware, and I think it leaves people not knowing what they want to buy, or what's even considered an upgrade.
