>What distos are hot at the mo'?
What distro are *not* hot at the mo? (appart from Ubuntu, of course)
>I take the point about revamping oldish hardware
Now think of it not as "revamping oldish hardware" but as "replacing your harware every 10 years instead of every 3 years" and look at the $ signs dancing before your eyes.
>but on a 30" screen linux seems like redressed Windows 3 to me
[I reckon we are only talking Desktop from now on]
egg-Jack-telly. Appart from the fact that your statement does not mean much (what with the miriad of distros, and more importantly, the miriad of graphical environments available?), most linux distros are developped by people who seek (and, sometimes, find) efficiency. This approach -usually- leads to very efficient work environments, potentially looking like crap (but efficient crap). Also, it the look doesn't please you, you can, well, you know, design your own. That said, it is possible, in the Linux world as everywhere else, to find bloated eyecandy GUIs (including several 3-D desktop environments). it is even possible to find graphical interfaces that put bloated symbolistic crappy-looking design before anything else (Ubuntu, I'm blandly staring at you now).
But the average user is hugely more efficient in front of an efficient specialized interface. It looking like crap is a plus: people tend to waste much less water and time when they have to shower with cold water than when they have a sauna and a jacuzzi. Replace "water" and "time" with "CPU cycles" and, err, "time". BOFH forever!
Of course the learning curve might seem steep, and when you will reach the ultimate "me and my computer think alike" monster nerd, your significant other will probably ditch you. But look at the bright side: by the time, if you're wise, you'll have installed a complete domotics system that allows you to control the doors and windows by blinking. The filthy harlot won't escape. MwahahahAHAHAHA.... sorry, what was I saying? Ah, just one little thing: don't appempt that if you are a genius of a filesystem developper but unable to do some cleaning. It most certainly will fail.
