I disagree with Jon for permanent real.
Give me a break... if Android was never announced do you think Apple would have been so aggressive with the App Store? Would Symbian Foundation have formed? Would all these great mobile developments be in the works? NO. Android was the catalyst for mobile revolution that gives power to consumers... and takes it from the wireless carriers.
Chrome is no different. Why can't Google use their resources to extend their product line? It's a LOGICAL transition and one that will AID their other products. They are setting the pace for innovation right now and the competition they create makes products, across the board, better. Even if you don't choose theirs... they are a part of the reason your "choice" is better.
How could anyone possibly to tell them to STICK TO SEARCH when they already have 80% of the search market? When you dominate so incredibly, you HAVE to be looking for other growth areas. They would be stupid not to.
The areas of growth they've chosen to pursue with Android and Chrome DIRECTLY benefit their search objectives. And on top of all of this, they really do put users/customers and the experience at the top of the priority list.
And yeah, I do have some personal benefit in Google's products succeeding but if I didn't believe in them to begin with... that wouldn't be the case.
