Well, I witnessed it today. HP's newest calculator hit the shelves of our
University bookstore. It is _simply_ amazing. I've got to rid myself of my
HP 28s and get this sucker.
Some things I noticed right off. The screen is much larger and more square.
The actual text dimensions are 8 lines by 22 characters, where the 28s is
4 lines by 23 characters. The LCD also has a sort of blue tint to it. I'm
not sure what causes this, but it does look better (sort of Macintoshy).
The machine itself is slightly larger than a 41. It doesn't fold like the
28s either. Rather, they have two (maybe three) shift keys for using the
several different functions of each key. I tried to try out the integral
solver to see if that was improved, but I couldn't figure out how to enter
the equation! Also, for 28 fans who are concerned that HP has gone backwards
to produce a successor to the 41 rather than the 28, be not concerned. This
calculator is much more like the 28 than the 41.
The salesman gave me a photocopy of a comparison sheet that HP put out. These
are some of the features of the 48sx that the 28s does not have.

That's it. The two-way IR sounds really exciting. I wonder how well it will
work across a room :-). And finally, the cost. The bookstore wasn't too
much below suggested retail. $350.00. I doubt that will drop for some
time because of the hardcore-upgraders like myself scrambling to get one.
By the way, if anyone wants to buy a 28s, loaded with time, fraction, games,
integral functions (soon to be posted), along with a nice handmade leather
case, let me know. I'd probably part with it for around $140.00 (during
spring break of course).
