i was looking at the mac minis earlier today and was wondering how well they performed. i will most likely be doing internet, iLife apps and maybe iWork or Office for Mac as well as some light video editing (with iMovie/iDVD). if i got the mac mini with 512mb of RAM would that be enough to keep the computer running smoothly and still have a few apps open at the same time. also, how well are the graphics being that it only has 32mb of vram. btw, i'm planning on buying the 20in ACD along with the mac mini if i decide to get it. is there a lot of lag time (i.e. start up/ shut down - opening programs, etc) with the mini? and one more thing, how easy is it to add more ram at a later time and is there 1 or 2 dimms for ram in the mini. thanks for any help.
