There's a Reason Snow Leopard is Sleek Under the Hood

From Walt Mossberg, regarding Snow Leopard:

One delightful change: Snow Leopard takes up less than half the room on a hard disk that Leopard did, and Apple says the average user who upgrades will free up about 7 gigabytes of space. On my 2008-vintage MacBook Pro, I gained back a whopping 14 gigabytes.

Anyone else think that perhaps one of the major reasons for decreasing the OS overhead is to fit better on a flash memory-based tablet?

Just sayin'.
