Before I ever used Maemo or a Nokia N-serie device I was googleing for a free automated mobile voicecall recorder app and after many hours searching I found one at a Maemo downloads page.
I never liked the design of the N900 so I decided to read more about the hardware specs. and operating system. A Debian base operating system HWKB, and multitask convinced me to buy my first N900.
After a year of usage I had to buy a second one because the device got bricked at way it could not be fixed within 48 hours by Jelly_Roll at the time.
Nowdays I own two N900 devices one for testing and another as a main device.
I use easy-debian, frcron,ssh and usb-hostmode on a daly base.
I don't pentest I use a birds feather.
