I personally don't think anyone should be worried. HTC/Samsung et.al are big companies with their own patent portfolios and deep pockets. At the worst they will pay the cartels and move along - business as usual.
If you were to apply the "oh $CORP got sued and lost a patent lawsuit - I might want to dump $CORP product" uniformly - you will be left with no products to buy in the mobile space at least!
Why is HTC being sued and not Android - Because HTC is an corporate entity that makes money off Android - Android isn't a corporate entity on its own - who would they sue if they wanted to sue Android?
