This is what I need: Springboard background, 5-icon dock, bsd subsystem, ssh, apps running in the background or mess with system files (e.g. Intelliscreen, Kate, Customize, BossPrefs, MobileFinder), and basic apps that Apple will never allow: NES/SNES/GENESIS emulators, Terminal, quake4iPhone, and vlc4iPhone.
Those above things, to me, are more important than a few cool apps. I'll wait until a public 2.0 jailbreaking method is safe and easy. ALSO, and even more importantly, we'll have to see what jailbreak developers are able to do to port their 1.1.4 apps over to 2.0.
