Sure, I'd rather have the decimal point in its own space like the 35, 45, 65, 67, 42S, 49G+, etc., but I find that it's just as easy to see this dot on the (later models!) 33S as on the 32S or 32SII. I have absolutely no problem with it. This is one of the clearest and most readable displays I've found on any calculator and, with its two lines showing what's going on with both the X and Y registers, a significant improvement over the 32SII.
The enter key location takes getting used to, but works fine for me, whether I'm using my left or right hand. The overall key layout is a bit weird, but also works ok for me, with good key action--and I have NEVER had a key fail to make an entry when pressed.
Quality? The 33S has it. I find that the injection molded case pieces are fully as well and tightly assembled as on previous models.
Just the improvements I already mentioned make this calculator worth getting. But then you also get 32K of memory, almost 100 times what the 32SII has! You just about never have to worry about running out of memory due to long programs or too many programs, as you did with the 32S, 32SII, and even the 42S.
Overall, I think the 33S is a real bargain.
First, some general comments. I judged the overall quality of the calculator to be quite good. The keys have a good solid feel, like traditional HP calculators. It has about 80 times the memory of the HP-32SII, and I found it to run about 2.5 times faster. The manual is excellent -- clear and very well written, and similar to the HP-32SII manual.
The HP-33S has a few new features that weren't on the HP-32SII:
- Both RPN and algebraic entry modes. (The default is RPN.) I use RPN exclusively myself.
- Several new functions: cube, cube root, integer divide, remainder, greatest integer, and signum.
- A menu with 40 built-in physical constants (speed of light, electron charge, etc.). This is a great feature; I was constantly having to look up physical constants and store them in registers; now the constants are built in.
- A feature to shift the exponent of a number in engineering mode by factors of 1000.
- Four-way cursor keys (as you would find on a PDA or graphing calculator).
- Two-line display (to show both the X and Y registers).
The HP-33S does have a couple of drawbacks:
- Most importantly, as others have noted, the decimal point (and comma) are WAY too small. The decimal point can be difficult to see, especially when it comes after a digit 2.
- The rather bizarre V-shaped keyboard is a bit strange, but not really a problem. It just tends to give the keyboard a bit of a cluttered look. I'd rather see a traditional HP rectangular layout with blue and gold function keys on a dark background.
If you are a science or engineering professional or serious student, I would recommend this calculator as the best one being made today. Hopefully HP will come out with an HP-33SII that corrects the design problems -- then they'll have a five-star calculator.
The keyboard is layed out very well. In addition, the v shape of the keyboard actually follows the natural curve that your thumb makes when holding this in your hand - so if you do a lot of entering with your thumb (like I do), it is actually pretty comfortable and natural.
The actual layout of the keys is very good. The most used functions are on the primary level and the ones used less often are included as part of the function key. The physics constants are included and although there were a number of comments about spelling out what the constant was, the calculator uses the standard symbol for each of the constants so if you use these constants often, not really too much of a problem.
I grew up on HP's (starting with an HP 25) and this calculator really follows the same progeny. It is solidly built and very easy to program. It has all the functionality that you could really want for virtually any level. The size is a good compromise between compactness and readability of the functions.
Great price for a very powerful and intuitive tool - well worth the investment.
