Most of us would read reviews on the net before buying any gadget. Sometimes finding the right gadget can be such a tough job. A good example was when I bought my digital camera. There are so many choices and selecting one you like can make you go crazy.
Testfreaks.com is a great site, which will collect the best reviews from professional sources, blogs and forums under several categories.
I say "will" because it is still in Beta. It will be officially launched soon. They already have some great reviews. Coming back to my story about digital cameras, there were so many choices and I had my heart set on canon digital cameras based on their reviews. However, I ended up buying a Panasonic Lumix camera. I choose that based on the features but mostly because there was a discount sale going on.
