That XKCD also has one of Randall's best mouseover-text comments.
Seriously, what is it with everyone and their dog thinking they can make a better phone than Samsung/Apple, despite having (usually) no prior experience, no team of engineers, and nothing but wishful thinking?
Perhaps the fact that "better" is subjective? I like my cheap LG slider a lot more than anything from Apple, or anything I've seen from Samsung. It'd be a sad day if they were the only two firms producing phones.
