I went ahead and pulled the trigger on a new one also. I too, had been using the machine that I got Mom, but once we sold the house and moved her into a nursing home, she didn't want it anymore. While it's a decent machine, it's getting a bit long in the tooth, and is not as quick as it once was.
Any went with one that has an Intel Pentium 7 v3, 8 Gb Ram, 1Tb Hard drive, and a CD Read/Write. Should be here sometime next week. All for right at four bills including tax.
