Well, with the loss of the ExpressCard slot there is now no way to upgrade a machine that was already limited simply by being a laptop.
People who used the slot to upgrade their machines were few and far between. and you CAN still upgrade the machine. You can add RAM, you can add a bigger HD....
An SD card slot can be done with an ExpressCard reader or a USB dongle (who uses those anyway?
That's one additional gizmo to carry around. And using those gizmos and dongles eats in to the battery.
Now, instead of a versitile slot that....
....no-one used....
we get a small memory card slot most people really don't need to begin with.
I bet the card-slot gets 10 times more use than the ExpressCard-slot did.
Apple says we don't need Clones/OSX licensing and assures us they can meet the needs of their users, but look what happens.
So what exactly DID happen? A noisy minority lost a feature? Of course Apple can't cater to the whims of every single user out there. If you feel that their systems are not suitable for you, feel free to look elsewhere.
This reminds me of the switch to Intel. Some people vowed to never buy a Mac again. Fast forward a bit, and Macs are more popular than ever before. It seems that there is a minority out there that will complain about EVERYTHING. Every change is fatal and ensures the utter doom of Apple. Yet for some reason Apple marches from victory to victory.... Maybe, just maybe, Apple knows about laptops and needs of people more than Joe Q. Random on some website?
It IS funny to read the comments that basically say "I never used ExpressCard-slot, but you can pry it from my cold dead hands!"
