I am new to Mac and need some advise on buying an iMac 20" w/2gb or Macmini w/2gb and a Dell 20" widescreen. I like the idea of the separate monitor, but is it worth the loss of speed and harddrive space plus the graphics. I am not big on gaming but would like to do some home movie editing and iphoto. Also should I go with bluetooth kb and mouse or wired. Thanks for the help.
