I was frustrated in more than one occasion with mobile sites that display on my stock browser. It ranges from a minor annoyance, when I have to click to see the desktop version of the site, to a major problem, when it is impossible NOT to get the mobile version of the site.
For example try googling any movie title and the word "ebert" and you get a result on top to read famous critics' review, however when you click on it you get to a strip down mobile site with no way to read any but most recent reviews. Google doesn't offer cache for Ebert website either. Opera mini browser displays full version though. I guess Roger would rather have people buy his books than access the reviews on the go :-(
Not even Opera mini browser allows access to the desktop version to many amateur adult sites. These try to make users pay money for content they can access free on their desktops! That's outrageous: if I am not willing to pay for the adult videos on my 20 inch screen, I am certainly not going to pay for the same content on a 3 inch screen !!
There should be a way to bring power to the people to access the content their device is able to display without resorting to rooting and complicated hacks to change own's browser signature. Are there not? How about any browser that mimics a desktop browser by design (or gives the user an option to control its signature) ? I'd gladly pay for such!
