Hi. I still have 3 Pismos all going strong, one I use at home and the other 2 used by my mother in law (!) and sister. Best cost-effective upgrades are 2 x 512MB PC133 RAM to take it to 1GB total, which is good to run Tiger 10.4.11 and all the apps you'd ever need (if you're still using a Pismo, i.e. you're not doing video editing, playing the latest games, etc.). The 2 modules of RAM should run you about $50-60. Note that they're compatible with the Titanium PowerBook G4's and G3 iBooks, so you would have no problem re-selling them in the future to recoup your money. Also get a bigger, faster IDE hard drive: as many GB as you think you'll need and 5400rpm, e.g. a 100-120GB drive should run you $50 or so. So that's 2 excellent upgrades for about $100. I've installed Combo CDRW-DVD units in all my Pismos to replace the original DVD/CD reader. Easy to do and there are LOTS of options out there: see xlr8yourmac for feedback on models. You can also opt for a PCMCIA card if you can't find the Airport card cheap. I use the Motorola WN825G, which uses the same Broadcomm chip as the Airport Extreme card and gives you 54g speed. It is recognized by 10.4 and 10.3 as a real Airport Extreme card, and uses the Airport sw. You can find them around $15-20 on eBay. You have to weigh the costs vs. the utility of the Pismo, but remember that all of the components are compatible with more recent computers and could easily be resold in the future to recoup most of your original outlay. And in the meantime you can enjoy your Pismo.
