I just want something to run my computer without sucking up all the processes and memory. Is that too much to ask? I guess I should go to Linux huh?
OK, I'm late coming to this one but anyway....
Better going to Linux? Very possibly, it depends what you want to do. I run Linux at home about 97% of the time - the other 3% is when I fancy a blast on LFS or rFactor. It does all the basic stuff - email, web browsing, IM and so on. If you
must use Photoshop (instead of GIMP), Office (instead of OpenOffice) or Visual Studio (no real alternative, IMO) then Linux isn't for you - and there are people I know that use obscure features of the first two that aren't available in the open alternatives. Gaming as well, of course - running Windows games through Wine has not been a happy experience for me.
But if you don't need Windows gaming and/or odd stuff in programs like Office/Photoshop/Flash/Dreamweaver/whatever then Linux is a completely valid alternative - it does all the "usual stuff" very well indeed, has alternatives for most of the unusual stuff although not all, and of course is free.
Getting back to Vista, as I've already said on this forum I really see no need to buy Vista. If you have a computer running XP then the chances are you have it set up the way you like it, and in my experience of the Vista betas (yet to try the RTM version, but that will change soon as we have to start testing stuff on it at work) then getting it the way you want it will be hard work. I know there's a lot of exaggerations out there about the UAC prompts, but it did really annoy me. If you get it on new PC of course it's a different story, but personally I wouldn't upgrade an XP machine to Vista - just not worth the money.
A genuine example - I'm currently speccing a new laptop for work, it's not my money and I have a reasonably free rein on what I get. It will have plenty enough horsepower to do the Vista thing, but I'm currently erring towards getting XP because the prettying up, better search, and other benefits just aren't worth the extra hassle with UAC, and that's without the security problems I expect from any pre-SP1 OS from Microsoft.
Sorry for the long post, I had a lot to get through having just come to this thread. The summary, all my own opinion of course:
Vista is not worth the upgrade money from XP
If you're getting it with a new PC, it is indeed very shiny and probably worth it, but...
be wary of security problems
Linux
is a genuine alternative. Try it - you might like it, you might not, but give it a go.
PS - dougiemeats - just a question about your comment on Linux & resources. You're on Edgy if memory serves, what's chewing resources? Just checked on my machine with Beryl, Kiba-Dock and Screenlets running as well as a couple of torrents and playing music, and it's on about 50% (no swap used) RAM and well under 50% CPU while typing this reply. Doesn't seem too excessive to me, so I'm a bit puzzled.
