Installed Tray Weather and received an API key free of charge.  Not as user-friendly as sWeather was and don't quite understand why the key was necessary but the program offers a lot of data and can't beat the price.

Reliable backup software is crucial.  I did a search for "backup software reviews" but not once was this mentioned as being top-tier.  Maybe those who've used it for some time can chime in.

12-2 UPDATE: Bought a Backup4all Pro license and am pleased with the program's performance.  It offers all of the file backup bells and whistles including differential, and the support has been good.  Even though they're apparently in Romania, the tech support staff has a good command of English and have promptly responded to my inquiries. Unfortunately, it can neither image nor ghost (like Acronis) but I've Macrium Reflect Free for that.
