I’ve listed three of my old PDAs for sale on eBay. It was difficult to give up my iPAQ 4155 but I’m sure it will find a new home soon. Our Zire 21 was a good friend when we needed a temporary fix while searching for a replacement for a Sony TG50 that never recovered from a bad fall. We got a great deal on a Treo 600 which meant that the old trusty Sony Clie PEG TJ-27 was an extra device sitting and gathering dust. I’ve had succes with eBay and old PDAs in the past and I miss my old Psions–the Revo and the Series 5mx and the Tungsten T3 that I sold on Half.com.
