I'll throw in another plug for Ding. Normally, I hate downloaded applications that run on my PC. Seems that the payoff is never worth it or it's some sort of spyware. But my husband downloaded Ding, and I haven't heard any complaints about problems with his PC. Better yet, we jumped on an awesome deal the other day...we fly roundtrip between MDW and MCO twice a month, so he snapped up tickets for under $130 for several upcoming flights thanks to Ding.
