Need advice on choosing a new Smartphone?

[Biosci]

I did some research and would like some feedback on these phones. I would like to know what phone is best suited for my interests.

Here's what im looking at:
-Iphone 4;
-Blackberry Torch and Bold;
-HTC Desire Z;
-Samsung Galaxy S;
-Windows Phone 7;
-Palm Pre;
-Droid X.

Here's what im looking for:
-Phone calls (quality)
-Texting
-GPS
-Connecting to Internet and Speed
-Battery Life
-Apps (I love my iTouch)
-Compact size
-Sturdiness (I dislike using a case for the above reason, however im very careful with my "toys")
-good camera quality (video if capable)

Im going with Bell (Canada) if it matters.

iPhone 4 - isn't always functional without a case
Torch and Bold - RIM is plummeting, i wouldn't suggest a blackberry to anyone anymore.
Desire Z and Galaxy S - both very good phones, depends on your preference of the interface. play with both before making a decision.
Windows Phone 7 - wouldn't buy one of these until they've been out for a year or 2 just because of the limitations that brand new OS's have
Palm Pre - No. quick software, but not enough apps also not a good camera.
Droid X - Not available anywhere exept for US Verizon at this point. but a fantastic phone.

Desire Z and Galaxy S are your best bet.
