It depends on which ecosystem you're most comfortable in and would use more. Both iOS (iPhones) and Android (Nexus One and others) have its plusses and minuses. If you are able to, try out both and that would give you a better indication which one works for you.
iPhone, believe me.
The Iphone is better but the new nexus one it better than the Iphone
the nexus one is better by far because is much faster internet speed and it's outstanding
I think "Google nexus one" is way better than all other smart phones specially iphone and blackberry You can check complete specification of Google nexus one here & also check new photos of google nexus one however now the iphone four is now out but theyl be stuck with that for a year when android will have a better device out in a matter of months nexus one still wins
The Nexus One has the bigger screen at 3.7 inches. The iPhone 3GS had a 3.5 inch screen.
According to this chart, it looks like the Nexus One has more features than the iPhone: http://mashable.com/wp-content/uploads/2010/01/nexusone-vs-droid.jpg. If you are a fan of T-Mobile, then it looks like the Nexus One is the way to go.
It does look pretty nice, and being able to use it on multiple providers is a plus over att and apples lock-in policy. I would personally wait for a similar phone with a slide out keyboard. if the nexus one had multi touch and a better online "app" store, then I would say yes... but as it stands there are still a couple things the nexus one needs to do to make me "upgrade" my iphone.
which one is better lumina 800 or iphone 4s?
The Android is currently the phone that is most similar to the iPhone and Blackberry. The Nexus One is the most recent version of this phone.
Android
it sure does and with android 2.2 its even better
The iPhone 4S is the most favorable of all three.
