Running 5 and 6 as well as D|S and several other graphics packages on an Acer TravelMate 5100 with 1Gb of RAM and bloody well not enough hard drive space.  Can you really ever get too much hard drive space?  It seems that the Poser and Bryce runtimes grow exponentially to the size of the available drive.

I use XP Pro and won't come close to Vista for at least two years...I don't know why I should pay to beta test someone elses software.

I'm saving my small change to have another Gb of RAM installed in September to see if it helps with those pesky out of memory messages.  See above for more details.
