The way Apple introduced Apps to Windows Mobile smartphones and ruined them, Windows Phone has introduced integration to iOS and Android and time will tell how it doesn't only ruin them, but also force them to copy it (that's what they do the best anyway).
That is just stupid. You're talking about the 2 platform that utterly dominate the smartphone sales and profits.
The market is new. Look what happened to the car market once it grew. I stand by my comment android is fragmented, buggy, crashing, garbage. iOS works good but its dated. Android now has quad core phones than feel or act no different than lesser phones. Some apps work and some don't it all depends on what version of android you have.
You know as much as I prefer WP UI, iOS is beautiful too. Also remember that features like swiping the homescreen to unlock and showing notifications on the homescreen were done by Android first. WP would not be possible without iOS/Android paving the way.
I think iOS and android are both awesome platforms. At the end of the day it is a matter of preference as all 3 platforms are very capable. Its all about which one works best for you. Currently WP7.5 is my favorite, however that may change as each platform continues to mature. It is better for us end users to have such competition in the market as each company tries to earn the one up.
I have both ICS and webos on my HP Touchpad and agree with @CHIP72 Webos is fantastic! They really got it right! I hope to see some open sourced webos handsets on the market in the future. My only beef with webos is that it never really felt optimized for the hardware it was released on. Even on my touchpad ICS is night and day faster and more responsive but lacks the polish that Palm and HP introduced.
