Some statistics presented by the Register about how Mobile Email can help us save time.

You bought into mobile email - what have you got to show for it? | The Register

The 2007 Ipsos Reid study analysing the ROI of BlackBerry deployment across over 1300 IT department in come up with some interesting figures:

* Personal Productivity: The typical end user converts 60 minutes of downtime into productive time per day.
− This equates to 250 hours per user per year in recovered downtime.

* Workflow: In addition to their own personal productivity, BlackBerry also allows mobile staff to keep work moving for others while they are out of the office. The average BlackBerry user reports that BlackBerry increases the efficiency of the teams that they work with by 38 per cent, a marked increase over the 2004 average of 29 per cent that was reported at that time.
− This equates to over US$33,000 per BlackBerry user per year based on international productivity per employee data.

 * Immediacy: The average BlackBerry user processes 2,500 time sensitive emails per year while mobile, and over 1,200 phone calls per year.
− The value of this immediacy is difficult to quantify, but can be reasonably estimated at over US$5,000 per user per year.

* BlackBerry ROI varies by individual and is conservatively calculated at a minimum of 238 per cent. This equates to a payback period of 154 days, or approximately 5 months. The conservative ROI for BlackBerry was calculated as 162 per cent in 2004. The increase in minutes converted to productive time each day can be attributed to the proliferation of BlackBerry among operations level staff who likely have more slack time in their calendars to convert than executives. The increase in workflow efficiency is likely influenced by higher percentages of staff with BlackBerry, which creates improved workflow economies.

Data Explosion

In just three years, the bytes of data generated by digital cameras, mobile phones, businesses IT systems, and devices will equal the number of grains of sand on the world’s beaches.
It’s a mind-boggling estimation from market analysis company IDC. But
it reflects the proliferation of devices and systems used by consumers
and businesses, said Stephen Minton, IDC’s vice president of worldwide
IT markets and strategies, during a briefing on Thursday.
