How many (HN) Gmail users still use the Gmail interface? I remember giving up on it as a primary interface in the mid-to-late '00s, my laptop was crappy and the interface had slowed down so much that it was nearly unusable. There was visible lag while typing a message on my circa 2003 cheap HP laptop (I was a student, it was what I could afford). It was like getting sent back to 1996 and typing out documents in Word on a 486 (In 1996, I was only typing at 30 wpm and would easily get ahead of the system. Type up a paragraph, sit back and wait while it appeared on screen.)

I've only used it since when needing to type a long form email or grab some critical information from an email while traveling and borrowing a friend or family member's computer. I haven't even done that in years thanks to smartphones.
