Once they add a Windows or Linux client I'll give Allo a try.

To me it's a bit distracting to abruptly interrupt a coding session and pull out my phone. Lately I've been trying to minimize distractions and stay in a terminal or development IDE as much as possible. I mentally view distractions similar to latency when accessing memory, something like:

  Look up info in terminal or IDE - comments within code, man pages, etc. <===> register access
  Desktop applications - PDF, Powerpoint slides, IM, etc.                 <===> L1 cache hit
  Google something (often results in reading articles, HN!, etc.)         <===> L2 cache hit
  Phone usage (apps, calls, etc.)                                         <===> Memory access
  In person chat (prone to rants/complaining, tangents, etc.)             <===> Disk access
  Meetings                                                                <===> Tape based storage :)
