Here at the Apple Worldwide Developer’s Conference, Apple announced a new lineup of MacBook Pros. The 13″ and 15″ models drop the Expresscard34 slot, in which we stuck our SxS cards for reading (or our Duel Systems P2 card adapter), replacing it with an SD card slot. The 17″ keeps Expresscard34, for now.

Remember when, not so long ago, SxS boosters derided P2 as a reflection of the past, based on an obsolete card format (PCCard, or PCMCIA, which stands for People Can’t Memorize Computer Industry Acronyms)? Glass houses, meet stones: looks like SxS, which fits in Expresscard34 slots, is also too backward-looking for the new low-end and midrange MBPs.

So what now? SD is the solid-state format of the future (or at least of today)? Should we be looking to Duel Systems to make an SD slot adapter for our SxS cards?

Then, of course, when we need to read P2 cards, we plug the P2 adapter into the SxS adapter into the SD slot… making the new MacBook Pros the turduckens of the data-capture world!
