You didn't read the article?
"MicroSIM is the smallest size currently available. It supports additional address book features, better security and a few other API enhancements *out of the box*"
So, you didn't read the part about the "new features" being available on USIM chips, micro or not? IIRC, the only difference between "mini" and "micro" is the excess plastic surrounding the actual chip, hence the ability to "hack" a normal USIM card into a "microSIM" slot. You're just cutting the useless plastic.
"Apple have a track record of popularising new interfaces and technologies. They did it with USB, with Firewire, with multitouch... and they were (in)famously the first computer manufacturer to drop the 3.5" floppy drive."
... and they were also the first ones in using SCSI as a HDD standard, first to jump into RISC/PowerPC, first in using 3.5" floppies instead of the 5.25" with the Macintosh ... all of these improvements were lost in favor of cheap crap by switching to IDE and x86.
I doubt USB was made popular by Mac, Firewire was better but it didn't quite take off, and dropping the 3.5" floppy *when they did it* was kind of stupid, as pendrives weren't that popular back then.
