We all heard about the rumors of a new, slimmer, optical-drive-less, high-resolution display, SSD-based MBP in the future. This got me to think of the difference between a 13" MBA and the upcoming new 13" MBP. Basically, the only difference would be that the Pro would have a non-ULV processor, meaning it would be slightly thicker for extra airflow and bigger battery. Now you would only choose between a slightly more powerful CPU or slightly thinner body. Other than that, they would be pretty much identical. Apple usually hates having products that are so similar. Also, if you think of the "Pro" branding, it originally meant that it had discrete graphics (before the 13" MBP), then after it meant it had a SD card reader and high-speed connectivity (FireWire then Thunderbolt). The 13" MBA now has an SD slot and Thunderbolt, so it's not any less "Pro" than a 13" MBP. Perhaps they could give "Pro" a meaning again and make it define computers with a discrete GPU. In that case you would have the 15" and 17" MBPs with discrete graphics, and the 11" and 13" MBA with ULV processors and integrated graphics. If there is enough demand, they could also come up with a 13" MBP with discrete graphics and 15" MBAs with integrated graphics. But then I think that would be too much products for Apple. They tend to not offer a lot of options and keep it as simple as possible. Thoughts?
