Well Susan, to be honest to browse Mudcat, play with CakeWalk 3 for MIDIs, use Hearme, and to run a few office programs such as Word 97, my Pentium 133 with 32Mb RAM running Windows 95 met my requirements although I think 133 was getting near the min spec for Hearme and I think is below the PalTalk spec.I upgraded when an opertunity to strike a good deal on swapping parts arose and the AMD K6-2 500 with 128Mb running Windows 98 more than met my current needs. If it hadn't have been for the storm, and a forced rebuild, I think I would have stuck with that for a couple more years.
My own FEELING (specs would have to be checked) is that any current entry level PC is going to provide more power than many of us need.
I think the most important thing to know is your software requirements. Then you can start looking for hardware to run that effectively - hopefully also allowing a for a little bit of "future proofing".
