Does MBA make a 13" MBP more or less likely? At first, I thought, "That's it, Apple just isn't going to make a 13" Pro Notebook." Now I'm not so sure. Apple could take many of the miniaturization features of the MBP and put them into a regular MacBook-sized product. With the extra room, they could put in a real processor, real GPU, express-34 slot, real hard-drive. giga-bit ethernet, firewire 400/800, optical drive, backlit keyboard, or at least some of these things. The MBA is a lifestyle product with a limited customer base. A MBP is a professional-product with a limited (and different) customer base. Why not make a machine for each group? The R&D would overlap, but I don't think the targeted audience would. Price it at $1799 and you'd have to figure it would drive additional sales, not cannibalize sales of the MBA. Of course, the small pro portable isn't the only product Apple has (thus far) refused to produce (upgradeable mini-tower, anyone?), so I know it might be doubtful they'll release one, but I'm just asking: it's not really any less likely because of the MBA, is it?
