Yeah, like anyone remembers being born on a particular day anyhow. As far as I know it's just a day my mom made up and had typed on a piece of paper.

Just celebrate your birth-week, and party any day you want. Heck, I'm sick of having a January birthday no matter what day of the week it is. I've decided I'm going with half-birthdays and celebrating in July. Why should a person be cursed their whole life with crappy weather on their b-day.

Something went seriously wrong in your figuring to come up with $500 million per person. It should be under $5000 per person or $34.5 billion total - if your run the numbers like I did below in Python (assuming these panels only produce for 8 hours per day, which is a number I just pulled out of the my hat).

Throw in extra for installation costs. It would be interesting to know what the total area is of NYC rooftops that have good sun exposure.

ny_area_sqmi = 302.6
ny_population = 8175133.0
ny_demand_watt_hours_per_year = 64500 * 10**9
panel_watt_hours_per_year = 230 * 8 * 365
panels_needed = ny_demand_watt_hours_per_year / panel_watt_hours_per_year
panel_cost = 360.0
panel_area_sqft = 17.6
total_cost = panels_needed * panel_cost
total_area_sqmi = (panels_needed * panel_area_sqft) / (5280**2)

print 'panels needed', panels_needed
print 'total cost $ %.2f' % total_cost
print 'cost per person $ %.2f' % (total_cost / ny_population)
print 'square miles %.2f' % total_area_sqmi
print 'percent area of nyc %.2f%%' % ((total_area_sqmi / ny_area_sqmi) * 100)
------

panels needed 96039309
total cost $ 34574151240.00
cost per person $ 4229.19
square miles 60.63
percent area of nyc 20.04%

With all the sensors onboard watching in all directions, you'd think it'd be easy to keep the evidence of the other guy's stupidity. In the case of a crash you'd probably have all kinds or proof as to who was at fault. Maybe these cars should have a "report-an-asshole" button that sends data to the cops. Someone who gets pinged by that enough times would maybe get sent back to drivers training school. (someone who hit the button without good cause too many times would also get talked to)

So maybe a live driver would have to be on better behavior around a robot car, knowing there's an unblinking eye recording exactly what's going on.

If a human with a net worth of negative $10^5 to positive $10^5 is behind the wheel when something happens, maybe one or two lawyers will take notice. But if a machine that was built by corporation X, which is worth $10^9, get out of the way of the lawyer stampede towards the courthouse that will look something like the running of the bulls in Pamplona. Just look at the unintended acceleration claims so far.

PC Perspective & Tom's Hardware also have their takes on this now. There's also an ongoing DiskCompare.com review roundup

There's a partial roundup of 5670 Reviews here, generally they seem pretty positive.

This page has a price history graph for the 32GB model (scroll down a bit). The price dropped quite a bit a couple months after the introduction. Hopefully the 64GB model will follow the same pattern (pushing down the 32GB model along with it ... $200 range maybe?).

Both the Seagate 7200.11 and Western Digital Caviar Black families have a 5-year warranty (see comparison).
