Weird for me to see all the love for Inbox in a thread about bloated webapps. I liked the Inbox UI a lot, but until it was spun down, I had an issue where each Inbox tab would eventually bloat up to 2-3 GBs. Considering I'd have 3 of those open, one for each of my Gmail accts, it quickly became something I couldn't use on my laptop (unless I refreshed each tab every couple hours).
