The real problem with CAPTCHAs is that people are paid less than $1 per thousand to solve them, mostly in 3rd world English speaking countries. To write a script to break every different CAPTCHA out there seems like a lot of work when paying a few bucks will do the job even better. I think this is an easy to use CAPTCHA, and they say it will work on any device. That.s good enough for me, as I type on my tablet, with tiny keys and fat fingers.
