The same application is now available for Windows 7. Combining a clock, date and weather service, all in one application. What makes this stand out from all the other gadgets it that the HTC Home Gadget makes heavy use of animations making your entire desktop into a professional weather and news (upcoming widget support) station.
Being a fan of the HTC phones (yes I have one, the Windows Phone version) I immediately downloaded this to my laptop. I love the weather and clock application on my phone and loved the idea of also having the same functionality on my PC. And my expectations were met.
The current release is version 1.9 which support 32-bit and 64-bit architecture, Aero, change of wallpapers, and different weather providers via plug-ins. There is also an upcoming version 2 (which is still in Alpha mode) which promise to support News (RSS ??) and some (yet to be disclosed) other new features.
