I have the same from cca. 2009 with SSD, docking station and 9-cell battery, running Debian and still going strong, mine was used for controlling my RPi-driven CNC router (cncjs).
Buy a BT headset and you're all set. My choice is the Poly Voyager Focus 2, now 3 years old and still going strong! I need it for work but use it for all the calls when I can. Look ma, no hands! And some privacy too.
Keyboard looks a lot like the one on my now defunct HTC Desire Z, my last physical QWERTY phone... And I miss it too much...Happy to see something like that again! 2011 memories
