I've been a user of Mathematica since version 2.2. I am a physicist by training and engineer by trade, and a bit of a poster child for engineering applications of Mathematica. The other M product people look at me funny but are secretly jealous.

comment How do I seamlessly migrate from the older Units package to Mathematica 9's Quantity objects?
I don't know how to do that. I was converting from the static list of known units in the Units package (which is stored as a readable .m file) to the new Quantity objects, not the other way around.

I also made sure that any Quantity I used were among those stored locally rather than those that make a call to the Wolfram servers. I have to work behind a proxy sometimes and entering proxy settings during execution of coded solutions is not acceptable.

@alancalvitti My intent was to allow the use of the units that were defined in the old (pre-9) Units package. Presumably, this package is no longer maintained as Quantity has taken over that functionality, so this was a one-time event performed manually. By manually, I mean with sloppy, throw-away code. However, if you like this approach, you are welcome to add your own units into the dispatch table.

comment Incompatible Changes since Mathematica Version 7?
@Szabolcs The original report was filed online, I did not keep a copy. Below is a copy of the reply from support: Thanks for contacting Wolfram Technical Support. Regarding the issue you reported, it seems this is an intentional design change. We have internal discussions on this and the argument from the developer is that "Setting $Context to $System on subkernels is necessary to make sure (new) system symbols arrive in the correct context on subkernels, because despite the MathLinkPrintFullSymbolName settings, system symbols do not have their context attached".

comment Incompatible Changes since Mathematica Version 7?
@Mr.Wizard Thanks for letting me know. I was not aware of circumstances where I could edit someone else's post. Also, it seemed presumptuous for me to edit your post. Should I just copy/paste the comment into the post as it is?

comment Incompatible Changes since Mathematica Version 7?
I can't edit Mr. Wizard's answer, so he is welcome to add this to his list at his discretion. In version 9, expressions evaluated in parallel default to the Global context. In version 10, expressions evaluated in parallel default to System. This causes shadowing when using ParallelNeeds on packages which are supposed to define global symbols, and leaks symbols into the System context. This has been confirmed by Wolfram support as a design decision, not a bug.

comment Best practice of passing a large number of parameters to functions
For completeness, the one-liner Plot[PDF[LogNormalDistribution[#mu, #sigma], x], {x, #lb, #ub}] &[par] works.

comment Is there an equivalent of Sum for And?
In version 10, the function AllTrue will do this documentation. It even short-cuts.

comment Entering scientific notation in an InputField
Thanks to everybody for their help. I am not quite ready to attack creating my own control type, so I will study these approaches carefully. I selected this answer because it gives the option of entering the number in normal notation as well as scientific.
