I've tried Dropbox and SpiderOak. I think I've settled on SpiderOak for now, since it is cheaper per MB and offers really nice, granular controls. For example, I can sync specific sets of data between different computers and backup some computers without syncing them to others at all (unlike Dropbox which syncs everything to everyone). Like Dropbox, you get 2GB free with no purchase necessary and the client automatically encrypts data in such a way that allegedly the company cannot decrypt it without you providing them with your password. It also counts your quota against the size of your data once it has been "deduplicated" rather than before (Dropbox does it before).
As an added bonus, while the client takes more resources when sending data (since it encrypts it on the client side), it idles much lower -- virtually at 0% processor usage -- than Dropbox, I found.
I mean to say Oxford American English Dictionary. The grand OED itself says:
2. fig. A condition of affairs or events of a character opposite to what was, or might naturally be, expected; a contradictory outcome of events as if in mockery of the promise and fitness of things. (In F. ironie du sort.)
It goes on to note this usage has been around since at least the 17th century.
Note the Oxford English Dictionary on ironic: "happening in the opposite way to what is expected, and typically causing wry amusement because of this." That a Verizon device makes an iPhone more usable than AT&T's own network is precisely that.
The trouble with doing something right the first time is that nobody appreciates how difficult it was.
