2. Mine do, it just takes some time. It's not immediate, but when I read on Gmail (Thunderbird or the web) or on my BB after awhile it will finally update one or the other but sometimes it doesn't either. But for me at least, it DOES do it... Sometimes...
5. Go to the main menu (where it shows all your icons) and hit the menu key (the BB logo) and you will see the option for "switch applications". This is your "task manager". Or, as RKU suggested, you can set it up to one of the two convenience keys.
7. The top row of icons in your main menu is what shows up on the home screen. Rearrange them by highlighting an icon and hitting the menu key. You will see the option to move right at the top. When you're done moving, click the trackball and it will drop the icon in place. I have mine setup to show my business gmail, personal gmail, bb messenger, SMS/MMS, browser and manage connections. I also rearrange my icons and tidy things away into folders when I don't use them much to clean up the menu screen. You can also hide icons and folders you don't use often or delete programs you don't need right from the menu.
8. They are semi-threaded. When you select a message from someone you are texting it will show all previous sent to and received from texts for that person, but they are not threaded on the main message screen.
9. This is why I have Manage Connections on my home screen. Just select the icon, uncheck WiFi and you are home free.
10. I only use Google Maps and Yellowpages (though it's slow and confusing to use

). Viigo (RSS reader/blog app) is good but tends to eat memory. And of course a few games to waste time on when you're not doing anything else
I used to be a WM guy (AT&T Blackjack, AT&T Tilt) but since I converted to BB I won't go back
