Go on let’s have em, what laptops are you all running and do you recommend for SP 2013 development ? The MBP a contender (surely not)!… Is anyone surviving on 16gb ?
UPDATE! Can you also add your laptop and configuration to this list : (User “Add to List”). http://list.ly/list/73V-sharepoint-2013-laptops. If someone has the same one, just vote it up.
If you are trying to build Single server that uses SQL Server and would like all services to run on it, MS recommends atleast 24 GB, 64-bit, 4 cores & 80 GB for system drive.
You can survive with 16GB if you are running the minimum recommended services for development environments. For information, see Minimum recommended services for development environments.

Wow … what a lot of responses!
