Google offers a LOT of productivity driven products, for FREE.
Let me ask all you Apple fankids out there, what did you get from Apple that was 'productivity driven' that was 'free.'
Logic Fail.
"Ad-Supported" is not "free". It is "no up-front cost", or "metered cost", in many ways, but "free" is a stretch. It costs you, the consumer, in time, attention, and (significantly) privacy.
Going way off-topic here, but ...
- Google Music (Apple is making you pay for your storage, Google offers free storage)
Umm, iCloud is free for 5GB of storage (whatever you put up there) and for unlimited storage of music bought from Apple. Google Music is in Beta and Google has stated post-beta it is likely to NOT be "free" (because they can't get a good ad-support model built around it).
Google Maps were definitely innovative, and a huge step forward. Google didn't do this for charity, though; they make massive amounts of money off Google Maps. They are ad-supported, both in terms of direct ads being shown on the page when using the maps and in the listings/reviews attached to the maps.
GMail was "innovative" in that it offered 1GB of "space" when others were still dicking around with 50-100MB of email quotas. I'm not sure that is really "innovative". The other crap Google has "innovated" with in gmail, labels etc? IMHO, not significant. BTW, for that "free" space, Google got a treasure trove of ad demographics information. As with most other major Google ventures, your privacy and attention are sold to pay for that space. Google makes MUCH more money off GMail per user than any of their paid-quota competitors did, because it is capitalizing on your ignorance of what it is doing with your data.
