(CNN) -- Almost three years ago Dell launched a phone called the Streak, an Android-based handset with a 5-inch display that was marketed more as a tablet with phone capabilities than the other way around.
Critics blasted the device for being too large. Most smartphones at the time were still 3.5 to 4 inches, after all. That was the norm.
We didn't see many more mobile phones from Dell after its blunder with the Streak.
Now let's jump to the present.

Last Thursday, Samsung introduced its new flagship phone, the Galaxy S IV. It also has a 5-inch screen, like the Dell Streak. But this time no one complained. In fact, the reaction was quite the opposite. Critics have been praising the Galaxy S IV's gorgeous display, which is slightly larger than its predecessor.
And suddenly the iPhone, which was once the standard for all other smartphones to copy, looks puny next to Samsung's new phone.
How'd we get here?
