I'm all for this type of internet music distribution, but what I really would like to know is if this will make audio CDs cheaper. My ears and my stereo system prefer redbook audio over lossy compression. So will this drive down the price of traditional CDs or will it raise the prices?
So you think we should wait until technology produces a more paper like reading experience before putting in the time and energy to get these texts into electronics form? Why not try thinking past today and spend a little time thinking about tomorrow. Electronic texts are important now and as technology improves, they will become more accessible in the future.

Does anyone know of a site that reviews phones in depth? I'm particularly interested in aspects such as UI, independent measure of battery life, comparison of signal strength, and "shoot out" type reviews.
No doubt, it is his cookbook style of book review that allows him time to accumulate the large number ("600") of reviews. Unfortunately they are no better than reading the editorial pap on amazon.com.

Bullshit. Vinyl is analog, hence has an infinite resolution and infinite bit depth.
Just because vinyl is analog does *not* mean it has infinite resolution and infinite bit depth. First off all real world analog sources are bandwidth limited, including vinyl. There goes your infinite (time) resolution. As for your infinite bit depth, do you really think you will hear nuances below the noise floor of your electronics?

...they used them in the ipod for some sort of playlist control mechanism.
The only place the iPod would have a piezoelectric element would be for its speaker. The iPod makes audible clicks when you navigate its GUI. Just one of the many small details that makes the iPod supercool.
Sounds backwards to me. I usually use Python as my "control program" You can extend Python with C or C++. And use Java libraries directly when programming in Jython.
You know, I never understood why there is such a RPM discrepency between IDE and SCSI drives. Is this an artificial distinction in order to rationalize the price differential between IDE and SCSI drives or is there a technical reason why this is so?
...overlapping browser windows. I run my desktop at 1024 x 1024. I find that narrow columns of text are easier to read than wide columns of text. Reading web content with maximized browser windows would make me look like I was watching a tennis match.
I am looking for includes things like: the resolution of their grey-scales, what degree of accuracy the motor steps at, how uniformly distributed the CCDs are in the arrays
The best thing to do, when possible, is to do the measurements yourself. That way you know exactly what *your* device is capable of doing, and not the *average* device from the manufacturer. You shouldn't rely on manufacturer's spec sheets for this type of information.
For example, you can get a quick idea of the bit depth of a CCD by measuring the noise floor of the output of a null signal and compare it to the output of a saturated signal. You will find that most *consumer* or *security* CCD cameras will not give you a full 8-bits. Even scientific CCDs which state that they give a full 8-bits are only under certain conditions with a specific type of average or weighted measurement. Don't trust the spec sheet. Measure to make sure!
Then of course you could also use your head. How uniform are CCD arrays (spatially)? Think about how they are made. They are very uniform.
Finally, you should talk to your final project advisor. What you are doing isn't Physics, it's Engineering. Sure engineering is part of experimental science, but shouldn't be the prime focus of a "Physics" project, IMO (was a Physics undergrad myself).
For a fairly comprehensive list of Python GUIs check out Cameron Laird's page.
Many interesting wrappers out there (PyQT, PyKDE, PyGTK, wxPython, VTK, FOX, etc).
I love choice, but part of me wishes that more effort would go into getting wxPython/wxWindows polished (and more fully cross-platform) to knock Tkinter from its status as defacto Python GUI.
Of course if you are in the market for a Python GUI, you should also check out PyQT in addition to wxPython. A nice tutorial for PyQT by Boudewijn Rempt can also be found here.

1. Capacity. Compare 120 GB vs. 2 hour VCR tape.
2. Quality. Compare best recording quality to HDD vs. VCR tape.
3. Programming Flexibility. Record daily/weekly over same program space, so instead of getting n copies you record over the same show slot.
4. Time shifting.
