Well, I just like to list things as there are articles written all the time that say you can't do work on a tablet, by people who don't use tablets of course or don't take the time to learn them. Yet, I did, for years, and it wasn't any slower than a laptop as far as speed of work and efficiency. I remotely supported major web properties, did coding, you name it.
Similar to what vacationhopefuly points out as well, for a "home phone", I use Google Voice (100% free) via a OBI202. So, $0/month for many many years now. Still have my Dallas number on it.
