The first generation of it kind of stunk because you couldn't download things to external storage, like a memory stick for example. The new version though, P5Q Deluxe is great, if all you need to do is turn it on quick and check your email, or get on instant messenger its perfect.
Dont make the mistake in thinking its a flexible OS that you can build into a PC without a hard drive though, it doesn't power on in 5 seconds, and its locked down big time.
