Personally, I would wait for about a year before upgrading to Vista. The first generation of any software has many bugs in it. Instead of having bugs and then patches for them, I would rather wait and get the version with less bugs.
The release i have at home works great with my hw.
We have also started testing Vista at work, but we normally use Dell PCs, and so far there hasn't been much problem.
My advice is to go for it, I dont know if home edition is really a striped version.
I am going to Chicago's MS Office 2007 official launch event and they have promised us to give a 120 days key for Vista with a free copy of Office Pro 2007 and Office Groove 2007 ;) Will tell you once I install it.
Every new software will have bugs and Vista is no exceptions, We have numerous issues with Vista just like we did with XP... It will take time to get the bugs out...
Vista allows 30 days grace period before asking for activation and if you don't it shuts down most of the features. You can extend the grace period 3 times by doing the following.
From an administartive command window type while in the windows/system directory.
To Reaem for another 30 days
"cscript slmgr.vbs -rearm"
Check status with
"cscript slmgr.vbs -xpr" or "cscript slmgr.vbs -dlv".
moreover I have installed vista it has kool effects…etc however if you are a user of browsing, movies here and there, and light stuff, I d say stick with XP till late June/July 07.
