Would you be willing to trade a 1mm of your phone's thickness for probably something like 30%-50% longer battery life? I would certainly answer yes, but it seems to me all manufacturers are convinced average user would answer no. Have we really come to a point where 'looking cool' is much more important than functionality?

Has colorful UI became such an important factor in choosing your phone? I currently have an old non-touchscreen s60v3 Nokia and it's UI is certainly fast and stable. With a few (free) apps installed I get enough one or two key shortcuts that I almost never even need to open a phone menu system. The screen is small (2" - so 2006...) but is partly reflective so I can actually use it in full sunlight even without the backlight. The backlight itself has fantastic range (something like 20 different levels). At the lowest level you can read only after your eyes have fully adjusted to a complete darkness - a feature that I _love_ as I often read ebooks in bed and find a stronger backlight irritating.
There is also currently no StyleTap PalmOS emulator for Android - an actual deal-breaker for me as PalmOS still has superior apps to Android. Take astronomy apps. On PalmOS you have three planetarium apps that are light-years ahead of the Google Sky. The best one, Astronomist, probably has something like 300-500 page manual just to cover all the features. Or LyME - MathLab 'clone' for PalmOS. There are a lot of 'toy' apps for iOS and Android but how many really complex apps are there, that would require >100page manuals? An ability to write apps in a scripting language is also something I wouldn't want to give up.
No, as things currently stand, I would definitely lose more important features by switching to Android than I would gain.

Am I the only one that will really miss Symbian? I am no developer but I really liked my low-end S60 smartphones. UI may not be as fancy but when it comes to functionality and performance/price ratio these were the best phones I have ever head. System-wide copy-paste, BT file transfers, WLAN tethering, true multitasking and background processes, video calls.... it had it all for ages. On-board Python interpreter with a full API access is also extremely cool feature that I believe no modern OS can match. I also had StyleTap installed and so I could run almost all of my PalmOS programs, some of which are still much better than anything that is currently available for iOS or Android. All in all, I will miss it. When I will be finally forced to switch to Android, I think I'll miss more features than I will gain by a fancy UI.

Seems the American astronomers still haven't got over the demotion of Pluto and are desperately trying to compensate :)

It's actually North America Nebula.

"making it the third most popular platform behind iPhone and RIM's Blackberry"?
Wasn't Symbian still on top?
