The problem with the stock browser is that it doesn't "remember" the user agent you set. Every time you open up the stock browser from new, you have to do the about:debug thing. Then, when you go to UAString, you'll see that it's already set to what you wanted previously. Then, you just have to back out, and the setting will take effect. Quite annoying. I just got Firefox, and I love it. The 'phony' add-on allows you to spoof user agents, and it will remember your setting. The tabs are much easier to access than the stock. I like the concept of using add-ons to customize the functionality of the browser. And I like the download manager. It tracks what files you've downloaded, and you can open/delete the files with ease. And most importantly, Firefox conforms the best to CSS standards and renders web sites more correctly than most others. Overall, it behaves very similarly to the desktop version. It has some kinks to work out. It did FC on me a few times. But the current advantages over the stock browser has already sold me on it.
