- Yes, initial payload size matters. But where's the true comparison about what each app is loading? How are the features and the UX? Would a power user be satisfied with Fastmail (e.g. search, filters, etc.)? (It looks nice, but none of this was discussed at all).
- The disparate email count comparison is excused way too quickly. Have you done a similar test with a brand new Gmail account?
- Anecdata. I've never had the page load problems as bad as described. 2-3 seconds, and I reload once every week or less. "Sluggish" is a weasel word -- what is sluggish? Searches return in ~1 second for me (~7000 emails, I'm not a saver.)
- You can turn off chat.
- Switching is never as simple as described, and forwarding is a fairly messy solution (and will only get messy as the author creates new login accounts and further forks his usage).
- Ugh, the "Google suggest" argument. For the record, the only suggestion for Fastmail is "Why is Fastmail down"
I clicked on "Goodbye Gmail" hoping for some substance or an interesting story but instead got feelings, anecdata and glossing over the problems of a real migration or search for a qualified alternative.
