One of the best things about modern smartphones is that they have full qwerty virtual keyboards so that there is no excuse for using text speech. In the mid-2000s and earlier, phones only had 21 buttons and you had to hit the 3 button three times to type the letter 'F'. And some carriers had character limits for text messages, so of course a lot of people used text speech. But by 2009 most people could afford phones with full keyboards, whether virtual or physical, so there’s no excuse. But even back in 2005, when I got my first phone, which was basic, I still used proper English when texting, and my parents told me not to use text speech when texting my younger sister so she wouldn’t get confused after she got her first phone.
