Well according to a search for "sues google" there's also at least Skyhook, Paypal, Ebay, Zynga and Paul Allen's Trollco. I'd say the lawsuits from Apple and Microsoft count even though they are indirectly suing Google.

Umm... I think you read my question wrong. Who's not suing Google? :-)

Ah, finally a chance to use this service ...

Hmm since when did my tablet grow a cursor? Are you using hacks? :)
