Developer takes exactly the same amount of time to boot, unless you've installed any other toys.

The player takes longer to boot on home power, as it waits for upgrading.

v1.03 takes longer than (I think) v1.00 as we stretched the drive recognition time (waiting for both drives to appear) as a couple of users had problems with their upgraded units. This means 2 drive empegs usually boot quicker than single drive ones. This is something we'll address in v1.1, storing the number of drives found when on AC power so that booting in the car is quicker on single drive units.
