Arlington, VA has recently replaced alot of their parking meters with them as well. Each space has an individual meter that works exactly like the old one did, except it can take a credit card as well. Problem solved.

Opera's made a very good living on their Mobile version, but I think they're in major trouble there now, thanks to WebKit. WebKit is a very good browser core, and it's free and open source (plus, it doesn't hurt that it lets mobile phone makers imitate Safari on the iPhone, since they're all based on the same core).

Look at the players that have adopted WebKit-- Apple, Motorola, Nokia, Palm, and Google for Android. In two years, it's taken somewhere between 50%-60% of the mobile browser marketâ" about half of that appears to be iPhone/iPod Touch.

Opera's problem is that, even if a "new smartphone takes over," if it comes from Palm, Nokia, or runs Android, it's going to have a WebKit-based browser on it, not Opera.

$3 million in revenue from Twitter in the last two years, versus what I count as roughly $100 billion in revenue over the past two years for Dell. That's not enough to qualify as a drop in the bucket. If I were Dell, I would laugh in Twitter's face if they demanded money-- they'd probably generate just as many sales by slipping fliers under people's windshields in parking lots.

That's why my first two troubleshooting questions are always:

1. Is it plugged in and turned on?
2. Are you sure?
