As I am on Ubuntu at the moment, I have to agree to the reviewer about responsiveness. Slackware (Vector) is far more faster en more stable than my Ubuntu Feisty 7.10 which I use at a daily base. The only thing that bothers me about Slackware is that you have to do the jobs yourself. By this I mean: compiling, making a package, upgradepkg, ... while for Ubuntu everything is easily available. Even by the programmers of the software homepage themselves. We have off course linuxpackages.net, and slacky.it, but still... Ubuntu is far easier when you have less time to figure it all out.
But to be clear: If you have the time, than speed and stability is still Vectors piece of cake!
This is my personal field experience. Don't kill me for that :p
I can relate to this phenomenon.
This is my own personal field of experience, Windows users tend to go with Ubuntu since it resembles Windows the most.
But I don't relate to this, I feel disgusted by Ubuntu when it reminds me of Windows.
I don't see that Slackware necessary is a bad thing when the user has to do the job done. I feel that this is a privilege of learning.
I have always wanted to learn about computers, OS's etc. and VL thanks to Slackware become the obvious choice and not Ubuntu.
Just my thougts...
