I ditched Windoze in favor or Linux over 9 Years ago, OK so I was a unix System admin at the time so I prefered to be working from the command line, but with the likes of Ubuntu there is now a real alternative to that bloatware that is packaged free with most pcs/laptops these days. Ubuntu is actually easier to use than that Vista stuff, and open office is easier to work than the Office2007 where they have hidden all the features that are not used by people who should have bought Microsoft works (for the reason they don't need those features).
OK, so there are some times when it apears the the Microsoft OS will out perform Linux, but these times are now few and far between and the only times I see this is where the third party software such as Sage products will only work on these propriatory Operating systems. Internet Explorer has its places too as it can be used to access all of the non standard web sites that are built only for IE, fortunetly the number of these is dwindling now too. And as most of these IE only websites don't support the new version of IE it won't be long before they are made to be complient with the likes of Opera and Firefox
That said, I always use tabs, very usefull when seraching for things in google, I right click on the links and say "open in new tab" then I can click on each of the tabs to see if the results answer the questions I have...
