His English you quoted is grammatically correct so I assume you have problem with the mental imagery invoked or something?
Honestly, I think it looks really bad for someone to whine about something that is grammatically correct, particularly when your own post is not as such.
'It' belongs next to the three periods, not spaced since it's part of the same sentence, not starting a new one. A space would be correct if you used four periods, which indicates a new sentence starting after a pause. The comma after pre-beta is wrong and shouldn't be there at all. Finally, you have a run-on sentence after "Windows 7".
Have a nice day.
Given that you want to start an argument, I am obliged to post a response.
I advise you to re-read what I had quoted, then conclude. There are a few grammatical errors and inaccuracies.
In your penultimate paragraph, you stated, "'It' belongs next to the three periods, not spaced since it's part of the same sentence, not starting a new one.". Would I be correct in assuming that you were referring to the first occurrence within that section quoted? You appear to have a fragmented sentence.
Given that no text was removed since said text was not a member of a source text, the requirement for the removal of the space is not compulsory.
The comma after "pre-beta", yes that needs to be in quotation marks, is not compulsory but is also not incorrect. Read the sentence aloud to yourself - without the quote, the sentence does not flow yet it is coherent. Finally, the two sentences are not independent. Allow me to rephrase it, though both are formally correct:
"It is not "way different" to Windows 7, it is in fact part of the NT 6.x family and on the same branch as Windows 7."
I would like to thank you for time in accosting me pertinent to this matter.
