The Dell Streak (shoutout to the other 3 people who bought one) had a 5 inch screen in 2010, a notable jump from contemporary phones like the iPhone 4 which was still 3.5", and other Android devices like the HTC Droid series which were around 3.7" and slowly starting to creep upwards to differentiate themselves from the iPhone. I think the largest Android devices you could get at the time were still smaller than 4".

That thing could really stand out in a crowd. I was at a baseball stadium for a concert that year, and spotted someone with a Dell Streak as I was heading down to the field. In a sea of people that was the one phone I spotted. I stopped to ask the guy about it briefly.

I also remember the viral, doctored image showing the reachability of phone screens which "proved" that 3.5 inches was the "ideal" phone size.
