My very first computer was an Emachines. It only had 128mb DDR. I later added a 512 memory to the 128. That was just one of the things I liked about Emachines. You can upgrade the memory without it being in pairs. Also the fact that I was able to do it myself.It lasted for about 4 years.

 Then about a year ago I purchased the Emachines T5224 with 1024 MB DDR and Windows Vista Home Premium. It has 250 GB hard drive, memory card reader,DVD rw,Intel Pentium D processor 820, Intel Graphics Media Accelerator 950. For Fathers Day I recieved a 2 GB Memory upgrade which I was able to Install myself....
