I am very quick navigating around in Windows and I am very familiar and adept with the hotkeys I use. But I do favour my screenspace above. There are tools you can use to improve you experience. Because I've used it for so long, I've got some tricks.
I'd show you my workspace at work, but I am sure there's data protection issues as well as others.

But I have a small 19" monitor and a secondary 10" monitor (used only for call logs) and I have loads of open windows to do lots of different things. I use Windows 7 at work and I make full use of the shortcuts and easy ways of moving through different Windows and tabs to streamline how I work. A couple of people I've trained are like "I wish I was that quick" and as a result, talk them through what I do when they need my help so they can get used to it.
Given we have to keep our talk time low with customers, yet provide a service, being able to quickly get information and access different windows helps keep that time down.
Alt+Tab and Start+Tab are my 2 most used buttons, as the windows are previewed, it's quite easy to spot what I need open. I am much quicker than 3-4 seconds (so they ladies s...wait a minute)
But I know what you mean about the extra 3-4 seconds adds up, especially with stress - if I find our database software is going sluggish and I'm trying to help a customer, there's moments of awkward silence and "sorry, but my system is being a bit slow", more stressful when it's an unhappy customer with little patience.
Not Windows' fault, in fact, Windows 7 is pretty damn smooth at work, faster than when we used XP, the downside i have found, is compatibility - some of our web software uses archaic Active X controls and incidentally we have to run in compatibility mode and has to be tweaked and new agents starting up a new computer don't realise the tweaks and rely on me to come around and "fix" their computer...mainly because it's quicker than getting the IT guy.
Also see you're using IntelliJ IDEA, RubyMine's brother,I am quite liking RubyMine, you share a similar love with Intellij IDEA or loathe it like the very Windows you reject!

Oh aye, I am preferring it to my KomodoEDIT set up. Has plenty of decent tools available. Plus the intellisense on it I have found is superior, which has helped me troubleshoot an issue better yesterday - for some reason a child of one database table is singular when there should be many...ain't figured out why yet, but I will have a read of the schema when I got time to see what I've done wrong. With Komodoedit, there's a certain amount, but isn't as good. I also thought it a "I'm being lazy" tool, but actually, useful troubleshooting, because if something isn't appearing when it should, you know there's a problem before you try and test for it.
