It also gives you enough privacy that only the percentages are revealed to other users, not your actual weight. You can check up on your status daily, and it will send reminders to challengers that haven’t updated their weights within the time-limit you set.

Unlike some of the other sites that appear “free”, then charge users to join your “free” challenge, TrackDiet.com is completely free – free to start, and free for members to join and participate.  The only thing you have to lose is the weight!

At a dollar under $20,000, it’s an expensive toy… but it does come with LED lights, a fully functional neural net brain – a learning computer, a fully automatic laser rifle, and enough gripping force to crush a titanium block.  Or maybe just LED lights.

Shipping might be a pain, but if you’re throwing away 20k just for a terminator statue, you might as well fly down to Texas, rent a one-way U-Haul, and drive that thing back to your lonely, empty house.

It’s about time somebody came out with a widescreen (16:9 aspect ratio) pair of video visors. Though they aren’t HD, and they don’t have a vga or DVI port, they apparently support just about every other video playing hardware. Now you can be just like Geordie LaForge!

That “4000″ festooned on its side boasts of the SideWinder X8′s impressive-sounding 4000dpi resolution, getting well into the spec-derby range and far beyond anything meaningful. Maybe numbers like that can help to justify its $99.95 price, or convince hard-core gamers to wait until February for its release.

It’s a pretty cool design, although I wonder if the convenience of not having to carry a music player would be outweighed by the added bulkiness and the necessity of sliding the PMP out of the headphones every time you wanted to change songs. It’s certainly an interesting concept, and with Skullcandy’s reputation for high-quality headphones, one that could do pretty well.
