Palm Zire 72
I bought this Zire 72 on eBay for just £6! At the time I didn't know if it worked or not, but when I got it and plugged it in to a charger it started up straight away! Excellent.
What I'd like to do with it is load linux to it, but I'm not sure it is ideal for that. I think I'll need a T2 instead for that.
I had a Zire 72 years back when they first came out and it is a great little PDA with a camera (1.2 megapixels) that takes video too.
Now all I have to do is work out what to do with it ...
