I bought a Emachine ET1810 for my grandson , so he could do his homework.  It runs Vista by Windows.  It has an Intel Celeron  processor with 420 @ 1.6GHz. It only has 2 GB of Ram, but that is enough for a twelve year old to do his homework and it can be upgrade later.  It has a 32 bit operating system, whatever that means.  Okay, it warms up fast and responds quickly and he does alot of multi-tasking on it.  It is really, really, low priced and your getting alot for your money.  There is a monitor that can be bought separately, tha is also a great deal.  The best part of the whole deal...
