The physical address the item is shipped to. There really isn't any ambiguity on this,

They are services firstly and yes they do just that, EVERY state tax, EVERY county tax and EVERY city tax. That is what they do. Big corporations pay armies of accountants because they want to do it in house since it's cheaper that way for them. The same reason that the biggest retailers may have lawyers and accounts needed to act as their own credit card clearing house, just because they do doesn't mean everyone does.

There are plenty of solutions on the market that don't require a full blown ERP or accounting packages for tax calculation and remittance. Off the top of my head I can think of Avatax but I know there are plenty of others. It really isn't THAT big of a deal.

That picture is of the Prada II which had a slide out keyboard. The original KE850 did not.

Perhaps I am misunderstanding the app but from the page it seems like it can only track "your" time off. Can it track time for an business with many employees?

It is a pretty large software package and support tends to suck if you don't pay but it is updated consistently is open, and once you get your head around things, pretty easy to extend.

Most developers I know myself included would never use WYSIWYG for anything other then prototyping layouts. That said I typically work with Dreamweaver in code view largely because it has decent site wide search, has pretty decent navigation features, supports subversion and handles code syncing reasonably well not anything I would pay what it costs for but since it was a company purchase and it does the job good enough not to piss me off, I use it.

A little like contracting smallpox to keep you from catching cowpox.

What they want taken down has nothing to do with defamation and everything to do with offering advise to people who have been sent demands by these people.

The reports outline how flimsy their evidence can be and offers effective defenses. This is nothing more then a SLAPP action.

NTSB has 400 employees that includes beaurocrats and administrative staff, those that actually investigate crashes is likely far far smaller (likely even smaller for FAA). You would likely have better luck sitting an inpartial jury in a town of 400. People tend to try to defend people they know and work with, it's human nature and often completely subconcious.

More importantly where can I find videos of the tests?

The answer is neither. The real true innovation is far more likely from ISM bands then any of the licensed ones.
