Because it's the truth?
What have been the major "innovations" from Google?
Gmail? Um, mail has been around far longer - Hotmail? Excite? Etc.
Docs? Again, word processing is not an innovative feature.
Google+? Oh, geez - don't make me laugh.
Maps? Map making has been around for thousands of years and online maps is nothing new, either. Mapquest, anyone?
There isnt a smiley available that says 'are you intentionally being dumb?' but I'd be posting it here if there was.
Gmail - Came out at a time when you had to put up with flashing gif adverts everywhere and storage for around 100 emails from the likes of AOL, Hotmail and Yahoo. Gmail came out with a 1GB email service (which was HUGE at the time, most people were still using floppy disks and CD's to back stuff up).
Docs - The first truly portable, and usable online document service which could be used for free, and would store your docs for free, while at the same time allowing collaboration, obviously acquiring Writely helped greatly here.
Google+ - A fairly new social network, which despite what some people believe, is actually growing at a good pace...I'm guessing you thought Apples attempt at a social network was better... 'Ping'
Maps - At the time when Google Maps launched it was the only half decent map offering. Mapquest didn't start offering satellite based maps until 2006 (a year after Google Maps launched) and still to this day does not provide any form of streetview type maps.
From the sounds of your logic your argument is 'Whats the point in Google maps existing when map quest exists'. If thats your argument you may as well say 'why did Apple bother creating a phone when there were thousands of them around all ready' - thats how stupid we're talking here.
Your whole Google hatred is flawed, Google have created some damn fine stuff, sure they have had their fair share of flops, but what company hasn't? I just find it laughable how narrow minded a select few people can be, you seem to hate something, but dont know why.
----------
It will be interesting to see if the rumored screen shots we saw were google maps or Apples own map data.
At a guess I'd say its Apple's custom 3d layer on top of Google Maps, it seems like the most logical way of working it to provide the absolue best app possible.
That being said, I cant imagine Google would be too happy about it, and would need significant licensing payment, which it looks like Apple isnt willing to pay.
