Back when working meant using pen and paper, I'd usually have the calculator sitting on my desk and operate it with one hand while holding my pen in the other. (Back then it used to be a huge annoyance to me that the otherwise wonderful HP-25, HP-19C, and HP-41C often weren't perfectly straight so that not all four of their feet would rest on the desktop. !@#$%^)
Nowadays, working usually means using a computer, and I use Free42, not a physical calculator. The simulator lets me copy and paste numbers between the calculator and whatever I may be working on, and that's a big plus.
Using a calculator when I'm not working at a desk or computer, I hold the calculator in one hand and use the thumb on that same hand to push the keys. If I had to use an actual calculator, I'd prefer the portrait layout because it enables this one-handed operation, and since my hands aren't very large, I prefer the Woodstocks and the HP-41 over the Pioneers and HP-48/49/50 series, in terms of ergonomics... But honestly, that's all moot since I just use Free42 on my iPod touch nowadays. I still prefer the feel of a real calculator, but since I use the iPod's PDA functionality every day, also running a calculator emulator on it means one less device to carry around. I do miss the plastic calculator bodies; the iPod's slick metal back is too slippery for my taste, and the textured plastic used on the old HPs felt much more secure in my hand. Whether the cases' edges are straight or slightly curved doesn't matter, in my experience.
