Hey i will response to your words tomorrow, just wanted to give a quick info:
I tried 5.5 Instant now and my first impression is very good! I think it is a lot better in the way it uses its language, less annoying single word sentences and bulletpoints and more focus on text.
The language is much more poetic and realistic.
It’s still not as good as 5.1 when it comes to personal language i am afraid but we will see, i couldn’t test it long enough.
Looking forward to others experiences
