Yeah, they may be an "evil corporate conglomerate" but they still GOT there by being good to customers, and they stay there because they continue to deliver products that attempt to meet the needs of their customers. Have I mentioned Excel 5? That was pretty major. Up until then, they had simply assumed everybody did what if tests with their spreadsheets; with some usability tests, they discovered that most people just kepts lists, and hardly ever used formulas. So they added features to make managing lists in Excel easier. And You know what? Excel 5 is pretty much the same as Excel 2003, as far as I can tell; heck, it even has VBA, being that VBA originated with Excel. (word had WordBasic, Access had AccessBasic, Outlook... well, I don't think it existed, And I'm not sure what powerpoint had, and I'm a bit to lazy to fire up my VM just for that.
Now, we have some conspirators among us... I won't name names... who go ON and ON and ON about their evil corporate methods and how they maliciously changed windows to not run on DR-DOS and because of that kicked Caldera right out of the market; but what is being forgotten here is that, at the time, Windows, while pretty popular, was not a necessity. All MS did really was change the decision from DR-DOS or MS-DOS to DR-DOS or Windows? And even then, consider that many PCs came pre-installed with MS-DOS already so saying that that single "malicious" act was what did Caldera in is purely speculation. It's evident that even if windows had continued to run fine on DR-DOS, that Caldera would have been repositioned out of the market by the time windows 95 rolled around; MS was being merciful by making it quick.
Now, that being said, the person who says this is fairly respectable; by which I mean, they are nothing like the 12-year old kids who start a free website that says that IE and microsoft suck and so forth and at the bottom have a "designed for Internet Explorer 7" logo.
