Occasionally I get asked how much a particular used computer is worth. Because computer technology continues to increase at a steady rate, computers loose their value quite quickly.
My general rule is that a computer looses about 30-50% of its value every year. A computer which was purchased at the store for $1000 might be worth somewhere around $300 two years later. Particular brands and technologies may loose value faster or slower, but generally, all computers loose their value quite quickly.
For this reason I recommend that no one ever buy a computer with the intent to sell it to someone else later.
I also recommend to most people that they do not buy more computer than they need right now. This means that you shouldn’t buy excessively more memory, speed, or storage because you intend on needing that extra capacity in a year or two. Ignoring this advice, people could buy too much computer that would be worth half as much when they actually need to use it all.

I have a friend who is trying to sell her 2004 eMachines computer. Please comment on how much you think this would actually be worth. After a few answers, or in a day or two, I’ll post how much she actually wants for it. Here are the brief specs that she’s posted:
-2.70 GHz Intel Celeron processor
-40GB hard drive
-Read/Write CD drive
-512 MB of Memory
-internet ready (LAN and Modem)
-Intel Extreme Graphics 3d video card
-Windows XP installed (I have the OS disc, and can reinstall a clean copy for you)
-Microsoft Office Student edition (I can leave it on the computer, but I can’t give you the install CD)
So how much is this worth, with accompanying keyboard and mouse? She also is selling her matching 15″ monitor, so she says.

At my place of work I now have two 24-inch monitors side by side connected to my Xeon workstation. I have Windows running on one screen, and Kubuntu running in a VM on the other screen.
At times, I’m a little overwhelmed about what to do with all that screen space. I leave my laptop closed so I don’t blow my mind.
For some programming classes, they allow you to turn in a project late if you had it done on time. What they usually do is look at the “timestamp” of the file, which is the time the file was last modified. Read the rest of this entry »
