I don't get the bitching about the new UI. What is he talking about when he says "pages that take several minutes to load"? Is he talking about the regular twitter.com UI? It loads in less than a second and is otherwise completely responsive.
When I read about this guy seeing over a minute page loads, all I could think was, something is wrong with your computer or network dude.
Not to mention what a pain it is to try to go back to where you were before which, while irritating on the desktop if you forget to open a new tab, is a significant disruption on the phone.
