Reading and drafting posts on the laptop works for me. I use the phone to read or post here only in desperate situations, posting from a hotel room etc. The phone's screen and keyboard are just too small for practical use.
But maybe I'm the exception. I tend to draft longwinded replies. I wonder if many read them clear to the bottom.
