But even then... look at the attached screenshot of Windows' task manager.
This is with Netbeans 6.7.1 (the over 500 MB javaw.exe process), SQL
Developer, Firefox, Outlook and Wireshark running, plus VirtualBox with an
Ubuntu virtual machine (configured for 1 GB and 1 CPU).

Only like 60% of the main memory used, because apparently VirtualBox is
configured to dynamically allocate memory. Now the VM isn't actually running
anything, but you'd have to go pretty crazy to max out the 6 GB memory.
Given that Micke mostly does web development, I doubt he'll have loads of
VMs all running at the same time.

Still, personally I would recommend neither an iMac nor an MBP, because I
don't trust all-in-one systems. It just restricts your options with little
gain. Isn't there some sort of Mac tower for a reasonable amount of money,
running a fast LGA1156 CPU and 8 GB of memory?
