There is a keyboard shortcut symbol that I couldn't figure out. Yesterday I stumbled across it (acrostic?) and it indicates the "Control" button. So, to get the Dock off my desktop to allow me to see some sites like Wired.com full screen I push down Control+Command+D and to bring it back I just do it again. I'm still learning lots of little stuff about how Macs have changed since I switched back to using Apple products for the apparent security OSX offers. I don't think it will matter much longer.
I think there will be an internet device that will have a button on it that will check to see if only the default OS is on the storage part of the device and anything else will be removed. Then, you can download whatever the consumer desires to a clean machine, and transfer it over to an off-line computer on a flash drive to use in relative safety.
I've been reading about the ASUS machine that only has a 4 gig SSD flash drive for storage. Now, the HP Mini-Note has come out with a similar one that has a few more features. I'm in the market for an internet only machine for browsing and e-mail. I hardly ever get e-mail any more since nobody discusses anything anymore on the discussion groups. People are discovering that people after all, are altogether too human.

I've considered the concept of "future proofing" with every new digital equipment purchase I've made. I'm not as good as this as I could be if I had loads of disposable cash in order to stay ahead of the hackers. Just this morning I read this article about how security is not about viruses and trojan horses anymore, but about browsers and how they can be compromised by specially designed web sites that doesn't care what your OS is.
