Well, you certainly will feel lame if you break out a windows laptop to show some pictures. Dam di dam di dam ti da (just waiting for the machine to start) dam ti da, nice car by the way, .... oh, the machine is updating some software, just a couple of more minutes... tam ti da... Ah, lets see, oh yes, the virus protection program needs to start first, da ti tam tam etc.
Im not really a fan of apple, as their customer service sucks and you pay a lot for the image. But for showing pictures to customers, i think the Ipad is the right tool.
