I love how damn near every product is now explicitly marketed for, if not tailored to, Arduino. Guides/tutorials/etc. don't even bother with other options anymore. They just straight out assume you're an Arduino person. Sad for pretty much every newcomer to the hobby.
In my own experience, whenever the topic of digital electronics/embedded programming comes up for the first time with a newly met techie they invariably say: "Oh yea, you mean Arduino. I just started learning that!". And it makes me ill. I know I'm not the only one, but I'm also aware of the prevailing culture of our time, i.e. if you ridicule that which is popular, brace for attack from the fan boys looking for pats on the back from the cool kids (i.e. the powers that be, e.g. mods). But yea, anyway... I suppose I should look on the bright side - they haven't started manufacturing "special" passive components for Arduino. Yet.

All other features aside, I assume this is much more sensitive/accurate than a BMP180 when measuring atmospheric pressure, so in terms of converted altitude readings, how much finer would the resolution be with this versus the BMP180? Does anybody have practical results they can refer to instead of calculations based on the specs? I'm asking because the BMP180 has proven all but useless for altitude measurements (same situation with the HMC533L and headings), which isn't surprising given the price, but I want to make sure the difference is significant enough to warrant the cost of the upgrade. Thanks!

Does the BMP180's calibration EEPROM store any values that are meant to be negative? Page 15 of the datasheet suggests that the 4th, 5th, and 6th value would be the only ones that can be typed unsigned, but I can't tell if that's just specific to the example. A Google search yields the same ambiguity. Does anyone have a definitive answer from experience?

Just remember that if you connect the RES pin to your MCU like I did, you'll have to add code to this library to bring it high during initialization, or add an extra routine to make use of it.
No public wish lists :(
