Or that most consumers don't have a choice in the matter (especially in regards to MS - I don't have a laptop running Windows & Office because I like Windows & Office).
That's the question, isn't it? If the user feels like they don't have a choice (and especially if it's because any potential choice has been intentionally squelched by the reigning monopolist), then it starts to seem dickish. There are plenty of alternative mobile platforms and thus it's rare to see people complain that they're forced into using an iPhone.
(raises hand) I complained about having to use an iPhone - mostly because of AT&T though. Thankfully, both Verizon moved in and I moved on from that job.
