I don't do work from my phone. My phone is just that, despite being a smart phone. I just hate doing web related stuff on it if I can help it. I like having a keyboard and mouse. Tether me to the wall!
Slow and tedious. Tried it. I don't have a lot of 4G in my area and sometimes the 3G seems a touch spotty. Not to mention I don't use my phone at work as I'm on the shop floor so I can't really check it anyway.
