Lol, I'm closing on 20 years now of beeing an avid google user. I'm so "good" at finding what I want that any bystanders usually tend to go "WTF did you just do now?".
Anyhow, I realize Nokia Phones are slightly better developed, for instance you can in fact change the search button there to google. But at this very moment I still feel windows phones as a whole are useless.
If you're an advanced user, you're better off with android.
If you're a simpleton, then iPhone is for you.
WP8 falls in between kinda sucking at both. It looks nice, but that's only until you realize that your new and beautiful home screen is now a total mess. I don't even have my contacts on it and yet I am already using almost 3x the size of the basic home screen. I actually find it harder to whatever piece of software I want to go to in WP8 then I do in android or iphone. And most tiles have to be either large or wide in order to be useful at all. Which means my effectual + Email + Calendar + SMS messages is already enough to take up the majority of my home screen. Add the camera, browser, calling, music, office and alarm icons to that mess. And you've used the whole thing and you gotta start scrolling.
Also, the tiles are not customizeable enough. For instance my weather tile keeps swapping back and forth between showing useful and useless info. But I can't actually lock it to the info I want.
I really hope windows will become a solid choice as a third smartphone platform in addition to IOS and Android, but looking at many of the choices microsoft are making. They're really trying to force me to use things like bing or skydrive rather then make those applications in to natural choices.

The tiles, arranging them in a practical way oftentimes means they don't look very nice. Yeeh, I just said that
