Though getting one will make you realize that everyone should have one. I find it frustrating that everyone I know doesn’t have one. Think of it this way: what if you were working with someone on a project/idea/plan that didn’t have email access at all (one of my electrical engineering coworkers still doesn’t have internet access at home). Wouldn’t you find it frustrating to not have a way to coordinate/share information other than on the phone. I suppose a fax could work, but who has a fax these days? At points I wish I could just email directions/pictures/information to a person rather than having to describe it over the phone, but I can’t because not everyone is capable of receiving the data.

You should upgrade for others as much as for yourself. Lack of connectivity should not be a hindering factor in collaborating with other leaders in your field and getting work done.
