I transfered my office phone to a cell phone (and added it to my current plan for $20 a month)... Saves me about $15 a month, and when 6pm roles around, I just turn that phone off so callers will go straight to voicemail... I also find it a huge advantage to be able to take it on the road with me. I have picked up serveral clients because I was the first person to show up and give an estimate (which I wouldn't have been if I didn't get the message until later that night). There are also some cell phones that will let you use 2 lines, so you would only have to carry one cell phone... although I prefer two phones. Also, just a note because there was some confusion with the morons at the cell phone store when I ported the land line over to a cell... it takes about a week to port the number, unlike porting a cell phone to another cell carrier which only takes a few minutes. Your land line will continue to work like normal until just seconds before the phone number switches to the cell... so you will have no down time with that number.
