So, is it worth to upgrade to SP1 now? Or keep with the non-SP1 version and wait for further feedback of SP1? Coz I think I'm going to install my Vista back, or might wait for XP SP3 release...

150% worth downloading Vista SP1.
Here are more of what I noticed after SP1 on my notebook Home Premium :
- games tend to load faster (strangely) (e.g. NFS Underground 2)
- faster UAC screen (which is great)
- pressing Ctrl+Alt+Del instantly pops-up the menu (no lag at all!!)
- faster copy / paste / data transferring, two and fro hard disk, hard disk to thumb drive, vice versa
- [my notebook oddity] - - when I hover my mouse over the round Start button, to the left of the bar holding it, the transparency would flicker once (Aero becomes a little darker). Now... NO MORE !!!
- found that most programs start-up faster, though very little improvement
- Aero interface is SMOOOTH...
- Control Panel loads up quickly (especially Uninstall option, where the tiny icons pop-up instantly, no lag !)
One of my the issues I had with Vista is start-up time. The Sidebar would take ages to load (everything else already load...). Now, it appears instantly with my Welcome Center window.
Only now I have the time to install Vista SP1 on my dad's new pavilion laptop...
Microsoft. You have done it..... At this moment.
