Apple doesn't seem to think so. They've decided to replace the ExpressCard slot with SD (secure digital) slots in the new MacBook Pro. Will other laptop manufacturers follow? I admit that I don't have a single ExpressCard peripheral. My Thinkpad X200 Tablet comes with WWAN built-in (through AT&T). I don't use it since I tether using my smartphone.
Will ExpressCards suffer the same fate as PCMCIA cards? Will they become extinct?
