I just tried out SliTaz last weekend, and really like the simplicity and speed. I also like the development philosophy that's based on minimalism and loading everything into memory.
I've got SliTaz loaded on a Sony Vaio VGN 2200E that's rockin' a Core Duo with 2 Gigs of RAM and shelled out a whopping ten bucks for a 4 Gig upgrade that should arrive later this week.
I'm still trying to figure out wifi, but I'm sure that will be all sorted out soon. Or, relatively soon, as by background is more psychology than tech.
Thanks for all the hard work put into this distribution.
