I bought my SR MBP 17" 2.4 Ghz, 2 gig ram and 160gb 5400rpm in september 07. Now, that was like a month before leopard came out, so im running tiger atm, and its veery smooth i reckon, since this is my first mac. Is it safe to get leopard now, i don't want to go through the vista **** again, all unstable and so on. And will i get any discount for purchasing my mac right before leoprad came out? ^^
