After using Inbox by Gmail on and off for a few weeks I thought that it was about time that I wrote a review of it.
Unlike the Gmail interface the Inbox interface is very minimalistic and takes a bit of getting used to as the tabbed category interface with the always on show sidebar has been replaced by a slide out sidebar that us the Hot dog menu (three stacked lines) that was first introduced in chrome to hide and show the sidebar along with a re-design of the category tabs.
