My optical trackball is setup so I move the ball with my thumb and use my fingers for the mouse buttons. Just rest your hand on top of it, and you don't need to move your hand at all. This thing has amazing accuracy, and works with anything I've used so far. The other thing I like is the wheel which allows me to easily move up and down any screen.... I don't have that on my SummaGraphics Graphics tablet. CD burners are great for storing files....But there is still no substitute for a larger hard drive. You need to have room to install your programs, to add all those files to Poser, and to save your renders. Then you can copy them to CD. It can get tricky bringing stuff from CD to Poser. You need to remember to uncheck the read only on many files, etc. I'm all for getting as much memory and hard drive space as possible. That's why I have a 20GB and 30GB. I also use the CD burner for storage. I've downloaded about every freebie file from Renderosity, and they're all saved to CD's. I will figure them out later. You may as well grab all the freebies ASAP, since some are taken down, retired, etc. It doesn't matter when or where you buy computer stuff. You look tomorrow and someone will sell more for less. I noticed with 320MB of RAM, my renders go really quickly if I use the default settings. I can boost things up a bit, and I may have to wait a few minutes for a render to complete...Not terribly bad. Oh, Valandar, my onboard AGP video chip uses 1MB of system RAM. You can see it listed when you right-click on my computer, and choose properties. The amount of reported RAM is always 1MB less than what is really there.
