I'm not sure if the memory will be a real problem, as 
many people have 128 MB nowadays, and in just a short 
time I think we'll be seeing 256 MB as a basic memory 
amount, with serious users going over 1 GB.

Add to this 10x virtual memory, and I think we'll be 
spidering for quite some time...

Not forgetting the 3ware 8port IDE RAID card and 8 pcs 
100 Gb HD which should be coming out real soon now. 
Nice to be reaching teralevels of storage on your 
desktop! Space for some links too :)
