Listening to your customers....
THAT is what Microsoft really should do a lot more often. And then I'm not talking about the several inquiries they perform on their websites ("has this information helped you?") or the rants you see on several blogs.
I'm talking about listening to the people who actually use, respect and like your products, preferably before they move on to something else.
I'm quite new to the Visual Studio environment, but what I've done is go over a lot of forums (even trying to help out people myself if I could) in order to get a good impression of what could be done, what couldn't and which caveats I had to look out for. I also found the place where users could make feature requests...
If the number one request (link to visual studio feature request site) is to bring back colour to the program which gets 12.500 (approx) votes and 1100 (approx) comments then surely its not that hard to realize that something is seriously amiss here?
(for the record: when you look at page 2 or further you'll notice that an average good idea has approx. 1000 votes or lower (800+, 600+, etc). So twelve thousand is really a lot!).
But... Nope. Microsoft has very quickly worked up a theme editor to bring some sanity back to the user interface, but the colours remain mostly absent.
NOW realize that this same interface is in par with the overall 'new' Windows look and feel. Office has almost the same look and feel to it, including the NICE TO READ MENUS. And although I know there is a difference between programmers and office users, the line that separates them can be quite thin (sitting the whole day behind Visual Studio, or sitting the whole day behind Word, Excel and maybe PowerPoint).
That is in my opinion Microsoft's number one problem today. They don't seem to realize (enough) that they're no longer in a position where they can dictate the world. At least by far in the same amounts as they could in the past.
So yes; when people dislike something enough they move on. If you don't want that to happen you really need to come up with something which will attract people's interest instead of scaring them off whilst you keep on claiming that "you redefined the way people work".
Get your act together Microsoft, before the empire comes crumbling down.
