My workstation has 6Gb's of RAM. While this might not be "an ocean" of unlimited potential, 6Gb's for general development serves me well.
I know Microsoft say 4Gb's is the minimum, but in my experience 6Gb's is already spreading it thin. If you're developing against Sharepoint 2010 you'll likely have at least 1 instance of VS2010 running and a pretty hefty SQL process. Needless to say Sharepoint is not a toy, its a pretty demanding server application.
I recently asked management for a possible upgrade on my RAM (6Gb's) because I feel it is not enough for Sharepoint 2010 development AND keeping a functional desktop (browsers, messaging apps, dev tools, vpns, rdc sessions, etc)
Do you guys think I'm being overly fussy, or do you think a Sharepoint 2010 development machine requires more than 6Gb's?
