Thanks for all the replies. Obviously the stable updated OS's will be an improvement from 10.6.8, but sometimes reading the problems of others who have upgraded and wish they hadn't for various reasons, one's slow adaption to progress is tweaked.
My steed has a 2.4ghz Intel Core 2 Duo and 4GB 667Mhz DDR2 SDRAM. Would any of you experts think that would be enough reasonable capability to stand an upgrade of the OS ? I know that I could look on line, but rather prefer the experiences and tips of people I know
