Android ICS actually looks very swish and like the most modern OS out right now! you should check out the Galaxy Nexus.
The nokia windows phones also look decent, but I don't really know about the UX since I've never used one of those. There's been some demoes of Windows phone being used with kinect for xbox, but not sure any of the current ones can do that.
From what I've read it seems like the GN is going to be on Verizon or T-Mobile. I'm on AT&T and don't plan on switching; I'm one of the people that likes them lol.
If you really want the Galaxy Nexus, you can buy it unlocked and use it on AT&T, but I think it'll cost you a lot of dough. Probably not worth it.
The galaxy is the iPad knock off and cheaper but is it better? It has interesting problems when you want to use the cam with yahoo and Skype. It does not work. It allows you to see someone calling you on the galaxy but the sending cam does not mesh up with these apps. Face time, Skype, yahoo and cam frog all work with the iPad but if u want to spend less money you have to take your chances with the galaxy.
What apps are you looking for and can't find on wp7?
You can probably get a Samsung focus for cheap and give it a month or two to try. Wp7 is one of those things that you have to try for a week or two to start forming an opinion on.
I would love words with friends on it. My lady and I play it very often! I had the Surround for a while and really enjoyed it, but missed my iPhone because of games. I have an iPad now, so its not the end of the world if I can't get WwF, but it would be nice.
I'm totally with you. I had both the Verizon and the AT&T iPhone 4 and got rid of both of them for basically the same reason you're considering changing -- it was getting boring. So, I currently have (on AT&T) the Samsung Galaxy S II Skyrocket, which I love. If you're looking for Android on AT&T, it doesn't get any better. I also ordered an HTC Titan over the weekend since it was on sale for one cent. I had a Samsung Focus before, so I've tried Windows Phone before, but I ended up getting bored with it waiting for Mango to be released. I'm excited about getting to have a phone with Xbox Live and Zune integration once again -- I missed both of those things.
I've played with Mango and really enjoyed it. I'm starting to lean more towards the Titan. Since I have an Xbox I can do the video share through it and use my gamer tag. Now my store just needs to get it in stock!
I figured I should put some closure on this topic. I upgraded to the HTC Titan and love this phone. While windows phone doesn't have all the apps I want, it gives me all the apps I need. But after seeing the Lumia 900, I want to sell my Titan and get that phone!
