I am planning to get 7.10 ubuntu. I have 7.04. I want to know if it has task scheduler kind of program always running.
I am looking for the following things.
1. highly reliable. (atleast better than xp sp2)
2. ability wake up from shutdown or hibernation.
3. abiliy to run programs in wine. (optional)
4. abiliy to hibernate/shutdown at specific time.
5. ability to sudo when required (optional)
6. simple bash shell like language if its command-line only (optional)

If there are processes/daemons which may interfere with waking and hibernating please guide me on what to do.
Laptop config:
core centrino duo 1.83ghz,512mb ram
intel 945gm chipset, connexant hd audio, 950 gma onboard.
