find the "seven" differences

Yes René, to make the Prime bugs free is the most important issue for HP. Not the key colors and not new features. After new features we get also new bugs, can be implemented later after a bugs free update.
We (buyers/users) all together are HP's client and we spent a lot of money to buy the HP Primes. We as client of HP expect an official statement with, a) excuses and/or an explanation why it is not possible to make bugs free software, b) a planning for the next bugs free update. In my opinion it's a bad attitude of HP to ignore/not inform there clients. This makes me so angry!
My advise to students, don't buy a HP Prime.

I was so happy with R10077, input statement bugs were solved but other bugs were introduced!
