Well, extremely stable so far on an AMD quad core 2G RAM machine.
I have an nvidia video card (7900GS) and the suggestion to install the nvidia driver was right on.
The direct to desktop first launch worked flawlessly, automatically detecting screen resolution and refresh rate.
Of course I couldn't resist "candies" and installed almost immediately the xfce4 + compiz .pet; this as well has been rock solid... I just can't get enough of moving my windows around to get some wobble

I am a huge fan of the quickpet tool for the most used applications.
I am absolutely impressed and delighted by the look, performance and stability of this Puppy. I'll try to get Luci243 this week-end and put some more mileage on and will report any findings.
Thanks to all developers, for the hard work and countless hours spent on this project.
