David,
Sandeep has given a great summary. As far as your analogy of diabetes vs B12, imagine if it were diabetes vs B2, B3, B6, and B12. That is one wireless does. It adds the B2 through 6. Makes troubleshooting a problem. Once you get rid of wireless, you speed things up, but you get rid of those horrible troubleshoting steps of disconnections, etc. And, hackers. Yes, they can break WPA2 and 30 character passwords.
To echo Sandeep, 4GB is probably all you need UNLESS you run VMs. VMs are great for running a few AC programs on multiple OS to try them first as far as upgrades, etc. In that case a 64-bit OS with 12GB of RAM allows you to run 6 VM OS at a time at 2GBs. Or less at more. Very cool to decide what hardware, RAM, etc. you can run on each. VMs are just too cool, especially on a server.
Speaking of Sushi, I think next weekend, it should be buy an SSD day. Gotta give Indy credit, he has pushed them on here forever.
Just to know, I think Indy intertwines SSD with othe big time network small and big info. I think we are blessed to have Sandeep on here. He knows a ton, but he is all things computers. And, I can connect you with SQL help second to none.
