Trends in Mobile Device Acquisition 1975-2011

---

We've all heard about the massive proliferation of mobile devices, the worldwide increase in the purchase of cellular phone. This image [does not include all mobile platforms] shows units of devices shipped from 1975-2011 and provide an interesting window on trends in the marketplace.

PCs on the downfall:

• iPad can no longer be considered a niched- volume of sales in its first 2 years places it within an order of magnitude of all PCs sold.
• iPhone, Android, iPad as the new entrants into personal computing have a combined volume that is higher that PCs sold in the same period [approx. 358 million vs. 336 million excluding Macs in 2011]

Three Phases or Eras

1975-1991: Emergence & rapid growth but also multiple standards and experiments

1991-2007: Microsoft Dominates

2008 - 2012: iPhone & Derivatives Dominate

Which Tablet Case...?

As I prepared to loan out the half dozen iPads that I was able to pull together - from my Faculty Development Grant and loan from our Educational Tech Director Al Weiss - I was faced with the question of how best to protect the devices to ensure the longest shelf life. This turned out to be quite the challenge. First off, there are a gazillion varieties to choose from. What I'll share here are the 3 models we ended up going with. I did also buy one standard case sleeve model seen on the right here - those provide good basic protection and come in at various prices - but as those are fairly basic no further explanation is needed. 

I ended up buying 3 different models through Amazon, and between using them personally and getting feedback from my students have some thoughts about what one might want to consider when looking for a case:

Kensington - KeyFolio Pro 2 Removable Keyboard, Case and Stand For iPad 4 with Retina Display, New iPad (3rd Gen) and iPad 2 (K39512US) - approx $50 AMAZON

10 Ways People are Using iPads

I've been looking a lot at iPads and tablets as I'm hoping to get one in the near future so that I can start exploring mobile learning. I came across this link to some videos on how people are using iPads---very interesting! I had seen the finger painting video before but some of the other ones - particularly the light video are pretty cool.
