Which Pre-Installed Apps Should can i DELETE?

I just recently got another impression since my first flipped out on me. I started going through the phone and realized there was a lot of crap ware on the phone that i didnt have on my previous phone since i deleted them. I started looking around and didnt find a topic on this right away so i thought i ask the question...Which of the preinstalled Apps should i delete? (for instructions on how to delete apps just use the search box). Below is a list of the apps on the phone:

ATT Music
ATT GPS
Yellow Pages
CV
Media MAll 2.0 (this is an update of the preinstalled version) [has a lock symbol with "sys"]
ATT Navigator [has a lock symbol with "sys"]
Make-UR-Tones [has a lock symbol with "sys"]
Mobile Banking [has a lock symbol with "sys"]
Mobile Email [has a lock symbol with "sys"]
MobiTV [has a lock symbol with "sys"]
MobiJV [has a lock symbol with "sys"]
MusicID [has a lock symbol with "sys"]
TheWeatherChannel [has a lock symbol with "sys"]
Where [has a lock symbol with "sys"]
XM Radio [has a lock symbol with "sys"]
Diner Dash 2 (DEMO)
JuiceCaster (DEMO)
Midnight Pool 2 (DEMO)
Monopoly Here and Now (DEMO)
Ms. PacMAn (DEMO)

Please offer reasoning behind your suggestions.

I went through and deleted all the demo games, even the dice.  It was intriguing at first, then became pointless soon afterwards!! 

Of the apps, I deleted EVERYTHING except Mobile Email (I use it for my Bellsouth account) Yellowpages- really good app in my opinion for being free to use with media, and CV- I like watching the news updates it offers. I also left ATT music-not sure why may have overlooked it or was unable to delete it... 

The weather channel is a pay app that is quite pathetic.  I used the free period then got rid of it. 
Mobile Banking is not configured for my bank, so i got rid of it. (most banks now do not offer the code needed to activate the service anyway)
I goatbroke MusicID- great program now that is is free!!
MediaMall is a ripoff seeing we can get almost any app or game we want from here anyway! (thanks Goat!)
The rest were not worth it to keep them on my phone- they took up space in my games and apps folder, so out they went. Some leave the icon on the menu page (ie ATT GPS, Media Mall) but do not open anything once deleted...

Before deleting, I used TKFE to upload them all onto my computer so I have them available if I ever want to reinstall at any time...

Have fun modding your phone!
