Eh, I'm finding myself disagreeing so far.
The full alphabetic keyboard on the 28S makes programming it much more convenient. I find myself writing my programs on the 28S and then translating them for the 48. I also think I prefer the key feel on the 28S, and I like that it is smaller in my pocket, as well. Additionally, there are some functions that I can't seem to find on the 48SX, such as "RCLΣ", which I have to manually key in.
I also cannot find a 'catalog' button (a very useful feature), and the screen on the 28S is far more legible.
Additional minor annoyances include not having a "roll" button readily available, requiring using the arrow keys (slow) or adding it to the custom menu (takes up space that would be nice for other functions), and that some shifted alpha keys are not printed on the overlay, requiring looking in the manual to find out how to type a "greater than" (>) sign or similar.
The two things I like more about the 48SX so far are its usability in one hand, the fact that it has the "I" part of "I/O", and the ability to recall, edit, and re-store the custom menus rather than rewriting them from the ground up to tack something on the end.

I don't own the manuals for the 48SX except as PDF's, but I do own the manuals for the 28S. Having paper copies is really convenient.

Thanks for the recommendation. I really prefer print books, but I am still thinking about getting that CD.
Is there a digital copy/torrent mirror somewhere, like with Linux distributions? Or is it intended to be "physical disc only" to provide revenue for HP Museum?
