Interesting points.
Especially about the shared data plans. If I can get internet on my iPad for just $5 or $10 more it would be a great convenience. Also, since Verizon doesnt let you be on the phone and internet at the same time, having a separate device that is internet connected would be helpful for travels when I may need to be on the phone (with a client) and accessing the internet at the same time.
As far as the INVESTMENT talk, the stock market can be an investment. Because people are losing money on it, doesn't mean its not an investment. There are also tons of people making big money on the stock market today, so it depends how you play. The whole point of an investment is to pay off later, but since theres no such thing as a sure thing, its possible that some investments lose money or value while others gain.
As far as an iPad or iPhone being investments, they certainly can be. It just depends on the pay off you want. If you want to save time, and an iPad can help you get things done quicker, then its an investment that pays off. You spend money for the iPad but then you gain time which has its own value.
Also, if you use the devices for business, they can be an investment because through those tools you are able to do your work better/faster/smarter and therefore generate cash flow.
Here's how an investment works:
1. You pay money or do something that you normally wouldn't do ("make the investment")
2. In return you get a benefit that you place a value on ("the investment pays off")
3. Sometimes, you don't get the benefit you wanted. ("the investment failed/was lost")
Key point about #2 is that the benefit doesn't have to be financial. There's many companies that invest into systems that save them time, improve their customer experiences, etc. Sure, the end result is typically more money in the end, but the investment itself is not always DIRECTLY tied to higher cash flow.
As far as more capacity or data being an investment, think of these scenarios:
1. You run out of space, and now you have to either give up using your iPad for what you wanted (by deleting things you want/need on it) OR sell the iPad at a loss and buy a higher capacity model.
In this case, buying more space is an investment as you are preventing yourself from losing money or functionality in the future
2. You need to access certain data on the go. Without the 3G connection you may have to spend money on a hotspot, better phone, etc. Those choices may cost you more in the end than buying the Cellular iPad to begin with.
In this case, the 3G upgrade is an investment because it prevents you from spending even more money in the long run on 3rd party ways of getting connected.
So yes, both of these upgrades CAN be investments and its not inaccurate to say that they are.
If you only use your iPad for leisure and theres no time/money savings, convenience, and it provides no value to you then in that case your iPad is a cost/expense and not an investment.
