Google: We do search that gives better results based on what the person actually wants. It includes a calculator, knowledge engine, currency converter and many more little features you'll take for granted all in one.
Hotmail: we do online mail
Google: We do online mail with quite a nice interface that includes chat features integrated into it, along with a labs section to fiddle with stuff. We give a lot more space for free. We are even trying to innovate with the use of priority inbox's and other features that didn't exist before. You don't have to use them if you don't want to though.
Nokia: We do smartphones
Apple: we do too, and added touch and apps
Google: We do smartphones that are open and customisable. You have a variety of hardware to choose from that suits you, and pretty safe ecosystem if you want that and a way to install other stuff too. We introduced desktop widgets and a few other useful features, although we probably weren't the ones to do them first, people seem to like them none the less. All this and funky integration with our other services.
Microsoft: We do Java too!!
Court + Sun: No you don't you do something different
Google: We do Android SDK that runs in a virtual machine using Dalvik bytecode. Oracle claims we violate their patents, which remains to be seen.
Everyone: We do instant messaging
Google: Me too! See email. Our chat happily and easily runs in browser and using a variety of clients, includes video and voice chat and phonecalls. Yeah others do it too, but are they as convenient if you're already using gmail?
Google: We do social too. We've tried it before and fucked it up. That taught us to give people what they want instead, and make it easy for people to lock down their profile, send messages to only those they want and generally try to respect their privacy (from an outside perspective. We do use your data, but it's free and we're an advertising company so what do you expect? Do you think facebook doesn't?)
Sony/Apple: We do brand-specific shops
MS & now Google: me too!
You've got me on this one...
Wow this really makes me sound like a google lover, heck maybe I am. But don't criticise them for making services that in many ways appear to be better than the alternatives in some but not all ways. Remember, you don't have to use them..
