Well, I haven't had the time to read all the posts in this thread, but at any rate, if I say anything that has been said, it will serve to confirm other people's opinions.
I got sick of my big, fat, clumsy Ubuntu installation. I got sick of KDE, too. I am looking for alternatives. I've been testing Puppy for a few days and here are my impressions.
WHAT I LIKE:
* Very, lean and fast! Just what I was looking for.
* Excellent configuration tools. They really work! Amazing.
* More intelligent than most distros what with the modularity, the use of SFS and how it is not afraid of using/booting many different types of media (HD, CD, USB etc.) and the bold statement of running as root!
WHAT I DON'T LIKE:
* The menus are an incredible mess. Holy cow, it's all over the place, and some menus have submenus, and the configuration tools are straightforward, but convoluted at the same time because there are so many tabs and submenus and options and detours and simply running of programs/utilities in the configuration sections... Aaaargh! Very, very messy.
* Lack of packages. The Ubuntu compatibility doesn't quite cut it. For example, I really need VIM and cryptsetup/LUKS. There are no Puppy packages and I can't make these work correctly from Ubuntu. I really would like to see more packages. That was the number one reason why I chose Ubuntu as my current distro. Please clap your hands and do the Steve Ballmer dance with me: packages, packages, packages, packages, packages, packages, packages, packages, packages, packages, packages, packages, packages...
WHAT I LOATHE:
* The package management system. Abysmal. The UI is very badly designed, very clumsy, doesn't adapt well to my screen size, I can't resize/adjust panes properly, the amount of information is not good enough (I am used to Ubuntu's Adept Manager)... Then I select one package and it takes too long to install. Too many steps and waiting around in the process. Even worse, I can only install ONE at a time! No batch operation. If I could at least select a dozen and go do something else while Puppy chugs along its lengthy installation process (like APT), it wouldn't be as brutal. But noooo, the thing forces me to sit through the whole ordeal because it only installs one package at a time and also because this annoying child keeps asking me to click OK in 3 or 4 dialogs for every each damn package... Grrrrrrr! This is even worse than Windows!
Being able to use Ubuntu repositories is nice, but besides the compatibility problems (messy dependencies, for example), it is not smart. We have to download the list of packages first, fine, APT does that too. But then it downloads and compiles the list... Man, that took forever! Excruciating. Then I removed two repositories and added other two. What happened? The stupid procedure went over the entire process again, not only for the new repositories, but also for the old ones again, again, again... And it took forever plus inifinity! Awful. Just damn awful.
Despite the problems, I love this distro and I want to use it. I can live with the messy menus and even the horrible package manager since I don't install new software that often. The deal breaker for me so far is the lack of support to cryptsetup/LUKS. I absolutely need that, really can't live without it.
Thank you for this opportunity.
