For me, I would keep the computer and ditch the car if forced to make a choice. It would certainly be challenging to lose either, but much more of my life and livelihood is related to the computer than a vehicle (e.g., studying, evangelistic website, bookkeeping job, ebay business, etc.). The bicycle and legs would certainly get more of a workout (and that would be a good thing)!
I hope others will share their thoughts (or perhaps some news?). I am curious if anyone else would choose to keep their computer over a vehicle.
