Hummers (the street legal versions) are also lousy off-road vehicles, much like a 5" smartphone is a crappy phone. But if you don't use it much for a phone, it can be pretty cool.Hummers are more powerful than most every car on the road, are they an advanced or somehow better car?
I use my iPhone as a 'phone' about 2% of the time, so I'll take a larger screen anytime, because using it for web browsing, watching movies, reading books and/or games is a joke. 4.8" is about my limit though.
