I decided to go with T-Mobile on my iPad Air - after 3 months I'm sold and will be switching my mobile as soon as possible. Apparently, T-Mobile will pay early termination fees for not only family plans, but also business accounts registered with a Tax ID.
I've found that working long hours is practical with regimented conditioning, much like training for any strenuous activity. If you jump headlong into a 60-hour work week, you'll suffer and burn out rather quickly. A slow ramp eases you into the commitment and tests your limits, gradually pushing them upward. It's also crucial to take down weeks every so often.
