So lately I've been trying out some apps that simulate Mac-style functionality/prettiness on a PC. Needless to say, they suck in comparison. But they get close. Here's some issues:
Yahoo! Widgets: Same thing as below on Switcher - I want to be able to hit the same button to get out of it, rather than having to click. And it needs to work better to not get "stuck" after the Heads-Up display. Some way to be able to use other widgets would be nice too. But overall it does an alright job. It's just not as smooth as it could be!
Update: I take it back. For some reason I decided to give Y! Widgets another shot (perhaps because negative feedback loops are really boring), and it randomly works. My current setup includes a 24-style clock (with sound at the end of the hour), an egg-shaped iTunes controller, stock ticker, a text-file read/write compatible post it note widget (exactly what I wanted), and weather. I set it up only to show on "Heads up", without any annoying dock.
Rocketdock: haha. This one is even better than OSX's dock. Wayyyyy better.
Switcher: a "peek" style switch, where I can hit the shortcut to see all windows laid out, and then hit it again once I've check on the window I want. This integrates the Aero-peek style functionality seen in Vista and more in Windows 7, and works like Mac's Switcher as well. I wish I could close windows when I see all the thumbnails. That would be really cool.
