I managed to pick up an HP elitebook 2560p for a ridiculouly low price on eBay,
I5 processor, 4gb RAM, 128gb SSD drive, Windows 7 Pro 64 bit system, all for $139, works absolutely perfectly, and fast!

Being me, I have to investigate all the options, so I've now got an Expresscard to USB 3.0 dapter installed,
another 4gb of memory on the way and a caddy so I can plug a second SSD drive in to it!
But there's one slot that I can't figure out, and I'm sure somebody here will have the answer.
Beside the slot for the WLAN card is slot/area I don't recall seeing before, any ideas?
Thanks
Chris
