FYI, I upvoted even though I disagree with much of what you've put. A number of these issues that you mention are only present with a lack of planning. If you go out and buy a computer with the intention of running Linux on it, you plan and you pick a computer with good compatibility. With each release of popular distros such as Ubuntu, compatibility improves massively. My Dad's laptop used to have issues with WiFi a few years back, now it connects fine (faster than Windows too) in Ubuntu 10.10. External displays? I've never had an issue with this and I'm actually typing this on a dual-monitor Linux setup. If you have an Nvidia graphics card then this should be fine. Again though, if you plan this isn't an issue. Software limitations, granted. Just like for OS X, there are professional wine layers which offer Windows software on Linux. But sure, that's not perfect. There is quite a bit of good quality software (plus, obviously, web applications work fine) and especially for development work. But this is definitely an area that needs improving. Personally I'm waiting on Canonical to release their own computer (or partner up with a hardware provider) for then there will be no issues with hardware compatibility or many of the problems you mention, for that is the reason they exist: attempting to run Linux on a device that was not designed specifically for it. Just my $0.02 anyway.
