I'm generally not a fan of being the first to try new stuff. Often there'll be plenty of guinea pigs willing to do that :P
There's a lot of hype surrounding it, primarily because it's related to MegaUpload. But it doesn't necessarily mean it'll turn out well. So basically, depends on how well it turns out.

The 50GB per account storage limit is perhaps bothersome, since we easily burn that in one day. The other thing is the claimed encryption - this seems to suggest that it doesn't use a standard HTTP upload process (what the script is designed for) and may require a fair bit of work to automate.
Tibb's point about their de-duplication is an interesting one however. I'm curious as to how they detect duplicate data when everything they get is encrypted.

Wooooot.... DOTCOM to launch new mega site this sunday, can't wait
