I agree that access to email now is a hit or miss. Way back when, before email, I would sit and wait by the phone waiting for a phone call that usually only came once a month or so, and then would be the worst connection on earth!

However, now there are so many options that are available for communication and many people rely on them more than ever. Unfortunately, in the "I want it now" society that we live in, we get upset when it doesn't happen right now. Phone service, email, and postal mail are still not readily accessible in all areas where someone can be deployed to. Also, simply due to the nature of what the spouses are doing, a phone call or email is not the top priority, sleep has to be put on the list somewhere.
While I am so used to lack of communication from my husband when he is gone, I do admit that I am guilty of checking the email multiple times a day and making sure my cell phone is fully charged at all times....just in case.
The spouses of today have it pretty dang easy, when my dad was in Vietnam all my parents had was regular mail that was not at all reliable, and before that I can only imagine how hard communication was when my grandfather was in WWII.
I guess my feelings about this are: positive--can talk/mail pretty much anytime and be in contact as much as we please; negative--too much wasted time sitting and waiting and worrying why you didn't get a call/email that day.
