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.
