Apple's attempt to raise prices on ebooks hasn't won friends on a forum where people are devoted to reading ebooks. Doing so illegally was asking to be savaged on Mobile Read.
That would remain true whether the perp were Amazon, Apple, B&N, Kobo or even Sony.
Also: Apple happens to conspicuous by design (literally), which seems to make them the
Boss Tweed of pricing conspiracies. Others might break the law, but Apple tends to be noticed.
It's a branding dream that can also become a legal nightmare:
"Price Different."
