The UI
Please be more specific and less emotional. The UI's on my Androids work fine. The back, home, and menu buttons are always in the same orientation and do the same thing in all Android apps.

Resource Management
New higher end Androids come with their own built in resource managers provided by the manufacturer which seem to work well. Buy cheap junk and you get well... cheap junk.

Sync
One of the greatest strengths of Android is that it does not require a computer to set it up and sync it. Contacts sync wirelessly with your GMail accounts. That being said, Motorola has a free desktop application called Media Link that syncs your photos, music, videos and more. It even grabs your music stored in iTunes.
DoubleTwist, Amazon MP3, and Google Music all sync music
Syncing files of any kind using GoodSync on your desktop also works well.

Support
I find Android forums more useful than Google or the vendor sites. Search and post to XDA Developers, Droid Life, Android Central and Android Police and you will find what you need.

Security
Research the app before you install it. Think!

Androids are for people who do not want to be boxed into a one size fits all environment. Yes they do require thinking and thinking can be hard.
