I double dog dare you to step into multiple manufacturing environments. Hey, guess what, Manufacturing does still exist in America, and *shock* we actually make enough money to stay in business. Stop looking at that @$#%#%# thing in your hand and step out into the real world. Come talk to those of us that actually have to support things like a building that has such large voltage drops that the battery backups are nonstop frying up....or making a Dos 6.22 machine try to just find that Windows Server 2008 share to pull it's programs.....
We are trying something as simple (and fun to design) as making the shop floor paperless. NOT AS EASY AS ONE WOULD THINK...when you actually break down where the paper is really at. You can't just take the paper away and shove a tablet in their hands....these guys work in 115 degree heat sometimes, with a layer of metal dust caking their fingers. Some of these guys have been in the business 40 years....and their eyesight isn't exactly capable of reading the dimensions on that drawing of a part that is 7 ft tall, and 5 ft wide on a device that is 5-10" in size.
Heck, I can't even get a mobile device that doesn't require Internet to function. Look at the Google Apps. Just using a Nexus to try to take a picture of that Aerospace part is already, out of the gate a huge no-no. Why? ITAR regulations. The App Dev is in the UK. You are taking a picture of a part that is required by ITAR regulations to not be accessible to persons outside the US. Just by buying that app from the Google Store made you give permission for that App to have access to the camera....which is the Devs....that are located outside the US. Any Google Apps and Devices are already eliminated out of the gate for our use.
The problem is with IT nowadays is that everyone is looking for a niche product to get rich quick off of, and not trying to really solve problems.
