If you love gadgets I have one for you right here. Correction I have found a whole package of cool gadgets for your windows, and best of all you can get it for free, no cost, Nada, nothing… you get the point.
The creator of the package has done his best to tweak the gadgets to fit nicely with Windows Aero (tho not all are transparent). You get 14 gadgets like Calendar, Email, CPU-monitor, stats, recycle bin, weather and one that I really liked; The Radio Gadget. You can choose from a range of music categories or add your own URL. Start and stop your favorite station with a single click.
The Email Gadget checks your POP3 accounts at intervals of your choice and displays all new and unread emails. Hopefully they can get it to work with Hotmail, Yahoo, G-mail etc. very soon.
