He, he, he.
What ever makes you think that!
Yes, by most standards it is indeed. However it seems to be running 7 SP1 within reason for most all I need, which isn't a lot. Certainly nothing processor or graphics intensive.
I bought it new with XP home on it and a 40GB HDD and 256meg RAM just about 10 years ago.
I have since put in a 160GB HDD and stacked it up to the limit of 2GB RAM. Other than those increases I have only bought another battery as the original doesn't last long - not that it really lasted very long when it was new (by current standards). It is not my main PC.
