How Users Read on the Web.
Also, this website doesn't have to be fancy, neither the layout nor the content. The first though of someone who wants to see something fancy is not usually "Hey, I think I will look at some random open handheld's website for some entertainment!". The exception are most people here, who already know most things about the Pandora(1GHz), and visit the website with the intention to judge about it, while actual users will want to visit the website with the intention to get information about the Pandora.

More than 10 seconds, and you break the flow. Users will often leave the site rather than trying to regain the groove once they've started thinking about other things.
10 seconds is also the time users typically allocate to examining a page before deciding that it's so bad that they're going to leave.

If the way the site looks causes it to load very slowly on slow connections, then then that's a bad thing, especially if the initial loading takes a long time. Even if you absolutely do want to ignore the
Fallacies of Distributed Computing (Wikipedia) in web design, then the current situation still is not optimal even for fast connections. I probably don't have to tell you, but if I'm not mistaken then the most influential things you could do on this site specifically would probably be to use pre-adjusted images (as opposed to CSS transforms),
PNG (lossless) optimization programs (such as pngcrunch and/or OptiPNG), and CSS sprites.
(Why I'm linking to alertbox so often? Becasue Jacob Nielsen is well-renowned for his knowledge and ability in the field of usability, and consequently his "alertbox" is a good source of information.)

In short, I currently consider this website broken mainly because it doesn't degrade well enough, because the content is too marketese, and because it's too much like an interactive print advertising (as opposed to a fluid,
responsive, and informative mini-library).
I have more negative feedback, but the other most notable things so far have been noted by others already.
