Good value in an old machine
For many years, my "work" computers were IBM ThinkPads. I carried mine with me between offices, and could plug it into a docking station in any of several locations. I could use it in a hotel, with limited access to company e-mail.
When I retired, I bought one as my "own" machine. It travelled around between the Essex house and the "bolt hole" with the same docking station process. I replaced that one a couple of times, too. Then the iPad arrived, and proved more portable, and the laptop got little use. Eventually, it stopped working and I didn't bother to fix it.
For the rare occasions I needed it, I decided it wasn't worth investing in a new one. Just before Christmas, I looked on eBay and saw how cheap they had become! I bid on and won, for £46, a ThinkPad T42 with Windows 7 Ultimate and MS Office 2007 (the full suite) installed. The previous owner wiped off his personal stuff but left the software. The machine is in first-class condition, apart from the battery being near the end of its life.
It occurred to me that I couldn't have bought the software (it's legitimate) for that price, never mind a competent laptop. All I need is a new battery (under £20 for an aftermarket clone). Good value, I reckon.
