I heartily recommend the following sites, and I hope others can add to this list. You can also suggest individual articles of interest on the net even if the entire site is not that great.
Cnet.com - everything under the sun.
Download.com - part of Cnet. Loads of reviews of software - the free and the not-so-free.
Slashdot.com - tech news and links.
Engadget.com - Huge site about gadgets, all the very latest stuff, links galore.
The Tech Lounge - Don’t know much about this site. I followed a link from the engadget site to an excellent article about the Megapixel myth.
For cameras, most people already know about dcresource.com and dpreview.com.
What tech sites are you selfishly enjoying without telling anyone?
