After selling my maxed out Wegener Media Super Pismo over a year ago, I immediately regretted it. Going even further retro, I picked up a PowerBook 3400c last year and tried to do a 'retro-project" by living with it for a year, but it was simply too slow and isolated (no USB, no printer drivers) to be productive.
So the prodigal has returned. I picked up another Pismo from eBay, this one a stock 500 mHz in pretty decent shape. However, it had been cobbled by some shadetree genius, and the processor card fried about a month later. Yesterday, a replacement 400 mHz daughter card arrived, and BONG, she fired right back up, albeit 25% slower than before. Still loveable, completely useful (as long as you're not a YouTube addict), and oh-so-sexy.
Of course, being the hoarder that I am, I've already purchased another Pismo, this one described as 'near mint' 500 mHz, with very low hours of use. Haven't decided whether I'll keep them both, but one will certainly stay.
This is by far the best laptop I've ever used, up to and including most of the current Intel aluminum bodies. The keyboard is so silky and responsive, with just enough throw and tactile response to remind you that you are actually typing words, I love going to the coffee shop and having other Mac users stop by and say - "Man, that's a sexy PowerBook - is that a new model?"
Sometimes I even say yes - it's a prototype - ha!
