=>You will not get what you want with one device (at least not in my experience.) A real training watch with GPS is not an mp3 player and vice versa

For tracking and logging relevant data (time, distance, pace/speed, heartrate, cadence) you want a dedicated device. Garmin makes some cheap watches at $100, but you're better off spending a little more and getting a Forerunner 2xx - these are great. You can also build structured workouts on them to do interval training, etc. Trying to use an Apple Watch or something else like that is going to be costly and will never be as good. Excellent battery life on these as well.

Music: I strongly advise against headphones for several reasons, but the ipod shuffle is probably the way to go if you must - small, no frills, long life.

Here's why I don't like headphones:
Situational awareness - tuning out to tune in to your music is dangerous. I also just generally believe that using headphones in public while moving (walking/running/etc.) is intrinsically bad as you're that much more likely to block others, get int he way, etc.
Headphones are frequently banned at events.
Training: if you're simply looking to cruise and finish the event, then this doesn't apply, but I think that's a poor approach to races, especially road marathons with reg fess at $100 or more. Needing music to run means you don't like running in of itself and it means you're not focusing on the running. Sounds crazy to noon-runners, but surroundings (on-road or off) should be enough stimulus when you're actually training - think about form, cadence, footstrike, etc. Running well - for speed, for distance, for anything - takes practice. When you stop paying attention or when you get tired, your form starts to decline, which is why it's so important to train conscientiously to develop good ingrained mechanics. This also makes you more efficient and helps with injury prevention.

There's really nowhere else to put this, so here goes:
Thank you dotancohen for all your comments. They are insightful, mature, and, perhaps most importantly, civil.

As a general on the discussion so far, I find it informative that the most vitriolic comments directed against Israel and Jews were posted anonymously; the posters are well aware that their remarks are defamatory and have no appropriate place in civil discourse.

Per the preceding discussion, the staggeringly different perspectives on life, the afterlife, martydom, etc. add a dimension to the conflict that is not easily resolved. As the product of a "modern", western civilation and education, I personally find it impossible to subscribe to any sort of notion of the promise of heaven, nor do I have any willingness to sacrifice myself for a religious cause. The asymmetric philosophy that enables suicide bombings, among other atrocities, has had an outsized influence on the conflict and global perception thereof.

Mark it as flamebait all you want:
"Peace will come when the Arabs will love their children more than they hate us." - Golda Meir

Article I, Section 8, clauses 12 and 13:
12: To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years;
13: To provide and maintain a Navy;

The Army and Navy are treated differently, which is a key point missing from simply pointing to the relevant clauses. There is a mandate for a standing navy, but armies were intended to be temporary.

While the Declaration of Independence is not a legal document of the United States, the fact that its sigantories were the framers of the American government implies that the Declaration means that it should offer insight into the founding of the American government and it quite clearly lays out points [1], [2], and [3], above, and in that order.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."

Jews do not proselytize, much less support killing those of other faiths. This is distinctly different from Christianity and Islam in which proselytization is normal and routine. For example, in my local newspaper this week, there was an ad from the local catholic church offering introductions to Catholicism and the opportunity to be baptised and join the church. Jews do nothing of the sort. Traditionally, those desiring to convert to Judaism are turned away three times to prove that they are genuine in their desires. The only Jews who do anything even remotely resembling proselytization is Chabad and they specifically reach out to less observant Jews with the intention of helping them become more observant - there's no interest in converting non-Jews.

Those are called horsepower (hp) if the seconds are involved (550 ft-lb/s)

And as an engineer in the US, I am very comfortable working in both sets of units. Metric is decidedly easier for calculations, but I second the earlier point of the more natural feel to English units - I do a fair amount of hands-on work and machining and everything is still in English, so that may be part of it.
The unit conversion argument isn't going to win over a lot of normal people, however, because during a regular day, how many conversions do you need to make, really? Most people compare apples to apples: this is 10 oz., that's 15, etc. And even for units with the same scale, metrics are compartmentalized - natural gas is BTU, cars are HP and even if I was running my car on natural gas, 1 BTU gas per second won't give me 1 BTU/s of power out. If you're an engineer, know both systems because there's a lot of legacy designs and parts. If you're not an engineer, you know what you know and that more than suffices. Who cares that there's 1760 yds in a statute mile (2000 in a nm) if you can estimate the width of your living room in yds/feet and can imagine what having to drive 50 miles to grandma's means.

Lastly, I don't know who tells people the military is all metric, but it ain't. It's mixed, but my work has been in English units when dealing with mechanical engineers and metric (not SI) with chemists - liters per minute, etc. all require conversion factors too and whether my code has me multiplying by 1/60e3 to put lpm in m3/s or 0.3048 to put feet in m (and vice versa), I really don't care.

While at Brown (2005 - 2009), Linux was not well supported by the University. There was, however, a Linux users' group who managed to solve most if not all integration problems, such that I was able to run Linux without any difficulties. Having purchased a new desktop, and now living off campus, I don't really know what the status of Linux computing is at Cornell.
For Brown, one had to contact the Linux users' group to learn how to make the VPN and secure wifi work, but it did in the end. The unencrypted wifi worked out of the box. I don't recall any classroom applications beyond Matlab from the CS department and that was available both in the department computer lab and for personal machines in *nix as well as Mac and PC. Other than that, there was never any software or applications for class that I would have wanted to put on my computer - the software that was used for homework and projects was either Matlab/Maple which are available as Octave and Maxima, essentially, and the rest were CAD and FEA packages that were far too intensive for most students computers - those were all run in a lab.

...but on the subject of our everyday compasses, they shouldn't be at all affected considering that they point to a lump of iron ore in Canada rather than the actual North Pole (hence a correction of ~-11/12 degrees when I go hiking in Harriman)
