In my experience, it seems to be a fairly common trait among CS majors to gradually acquire a large amount of various makes of computers in various states of operation. I think I maxed out at 3 during last year (laptop, desktop, crufty desktop) and managed to bottom out at zero through a hybrid of donation, disposal and deposit. This was a very strange situation, to be a CS major, working for a major technology company, yet owning only two devices capable of running a linux kernel (my phone and my iPod, you own more computing power than you think) and nothing capable of having a keyboard plugged into it.
Upon arriving at work I was presented with my laptop (1.8GHz Pentium M + 1 GB RAM) as well as shown to my development desktop (3.4 GHz Pentium 4 + 2 GB RAM), which is all well and good, except for some of the more draconian restrictions on personal use. Today however I obtained from the company an 833 MHz, 512MB clunker of a laptop for a ridiculous bargain of $60.
Woot.
And today there was sun.
