Well, Beta 4 dropped and that's the magical number for me. Running it now, and so far my first thought is about what I expected: what the hell did they do to iMessage? I used to be able to turn predictive words off by swiping down on the screen, but now I have to go into the settings menu. That's stupid. The new banner on the top of each message window is massive with the contacts name and photo, or the contact's first initial if you're actually an adult and don't have contact photos like most people I know. The Send button is even smaller now than it used to be, which is annoying as hell if your return button is set as page break and not send. Instead of just the photo icon to the left of text entry, now there is a plethora of useless options you can't turn off and will probably never use if you're older than 24. Basically, 2/3's of the screen is now occupied with noise instead of actual text, which kind of annoying for a texting app. If it bothers me this much as a 36 year old, my elderly parents are just going to be thrilled.
