I like Puppy too. I bought my dad an old 700 mhz laptop with 128 mb of ram. Puppy runs on it like a champ. He uses it every day, mainly for getting on the Internet and light word processing. He can even share files with his Windows XP computer through the network.
I have just under $100 in the whole deal, including the wireless card.
I keep the CD in my laptop for when I need to get on the internet in seconds, rather than minutes, from turning it on. It’s a fairly new laptop, but Vista wants several minutes to load, and then it wants to download and install updates, and then it wants to reboot, and then it will think about letting me do what I want. Puppy - 75 seconds from hitting the on button to posting on FR.
When flying, the plane could be landing before I could get online with Vista.
