Apple makes up ~75-80% of the north American market for smartphones (slides a bit higher for android in Canada than the USA )
Worldwide *smartphone* use is still largely apple in more affluent countries, and android in other countries. Business users HEAVILY skew towards apple in NA.
Android is also bigger outside of the pure smartphone category and many in the business look a the metrics with a grain of salt as it is hard to pick out which is a smartphone and which is a different android device. All qualified evidence points to android being between 60-70% of the general worldwide market, with iOS being ~70% in "first world" countries. Android dominates where price becomes the major driver. It also means the phones are... substandard.
Yes I know, this is overly pedantic, but it is what it is.
As for the comparison, Tesla is IMO a more successful BlackBerry. Great product, does what it says on the tin mostly, and is well ahead of its competition. The biggest issue BlackBerry had was they were convinced they were better than everyone else and were slow at new products *cough*cybertruck*cough and each of their new products were released about two years late. Look at BB 10, or even the playbook and the lack of features/timing to transition to 10.
Tesla is better situated and I think doing a better job than BlackBerry did. They had the BlackBerry messenger, which locked everyone into their framework. When they needed to pivot and bring in computers or other ways to tie into BBM, they failed at it. People hit the wall on apps and waiting on OS, then started jumping ship. Tesla has the charging system, but realized they CAN'T force people to choose, open it up to others to maintain the branding and income. So you continue relevance.
Releasing updated versions, like the highland, is key to keeping the pressure and market ownership high. Apple does a FANTASTIC job of release schedule and hitting the customer needs. Tesla is.. ok. Hopefully they will get better as they continue to get their build process more and more locked down.
