Yeah, it sounds like you've had some really bad luck with hardware.

Since you asked, for what it's worth, I invariably run Debian-based distros. I haven't touched Ubuntu since they decided to get weird with the interface. This laptop is a ThinkPad X61T running Linux Mint + Cinnamon, which is only "okay" - little laggy at times but it works fine. Surprisingly, the fastest-feeling, stablest, easiest-to-use machine I have is... the ancient EeePC. Standard Debian + MATE desktop. The thing about Debian is, if you can put up with somewhat out of date software, is it just does. Not. Break.

I don't really understand where your problems with multiple monitors come from. I just plug 'em in and they work. It's been a while since I had a desktop with an NVidia chip - all my laptops have Intel graphics - but NVidia's self-extracting installers have always worked for me (although they're built against the kernel so you might have to re-run them every upgrade).

I've had the repository problem you describe, long ago - the UK repos were being weird so I switched to France, which worked fine. Nowadays though all you have to do is use http://httpredir.debian.org/, which will always serve you the file from the fastest place it's available from. Never had an issue with it.

I guess I won't deny that it can sometimes be a hassle getting things working just right on a fresh Linux system. But at least you only have to do it once.
