I was just rewatching the Jobs-Gates D5 appearance which is a laundry list of Gates raising technological transitions that Jobs in fact installed into hardware and software over the next 5 years.
One of the issues raised was standards. Once standards are arrived at for leading technologies it facilitates convergence devices. Examples include the mouse, GUI interface, Ethernet, USB, video file formats, html, java, and many, many others.
So when someone announces that they are adopting micro-sim, thunderbolt, USB3, 802.11n, bluetooth 4, or LTE, this facilitates a wide range of device interoperability and lowers the barriers to market growth and the path to the next standard.
Micro-sim facilitates devices that have more net volume for other things. SIM itself is a technology to lock a user to a network since it is technologically possible to have simless devices.
But once you have surrendered to the business decision of your network to compel a sim, you also get access to someone's multi billion dolllar investment each and every year for capacity, new standards and protocols which deliver capacity and speed, and the knowledge it will continue throughout the 2 year term you just committed to and beyond.
Keep standards coming!

Rewatch D5 on podcast. It is an interesting look back in a time machine where you already know the final answer. You will have the strange experience of thinking, "I have that, and that, and that too", dozens of times.
