OK, the iPhone 4 may suck as a cell phone, and Steve Jobs may well be a jerk, and the whole friggin' company that is Apple may specialize in arrogance and overpricing, but. . . .
What before would have required lots of high-end equipment, crews of technicians and a cadre of special-effects geniuses now can be accomplished by a plucky -- Did I just write "plucky"? -- little crew of young filmmakers.
With an iPhone that costs much, much less than a color television did when I was in college.
Now, whether "cool" actually intersects with "necessary" (especially in light of the team of trade-offs and unintended consequences we hitched our wagon to on the trail to high-tech Nirvana) . . . that's another conversation entirely.
