Last week, PC World magazine released the winners of its 2006 World Class Awards. Topping the list was Intel’s Duo Core CPU followed closely by AMD’s Athlon 64 X2 Dual-Core. I thought it interesting that Craigslist made #3. I loved that Firefox 1.5 ( ) made the list and quite high as well at #12. Good for the Mozilla Foundation and in the back of my mind, I still sentimentally think of them as Netscape. Also on the list is Mozilla’s Thunderbird e-mail client, which I also use and depend on. I do find it interesting that Yahoo! Mail made the list, but Google’s Gmail did not. I have used both extensively and Yahoo! Mail’s spam filtering capability has just degraded (or at least not kept up) to the point where I can’t use it any more. Oh yes, for a more extensive comparison of Web-based e-mail services, check out our review. It’s a bit old, but most of the info in it still applies today.
