Detailed information
Link: Sandisk
Yet another model of the Sansa line from SanDisk. The Sansa Fuze is, in Dick's own words, half way between the Sansa Clip (Episode 493) and the Sansa View (Episode 459): a fusion of the two. It plays the usual music and video files, and Audible Books, 1.9" LCD screen, about the size of an iPod Nano.Available in 2, 4 and 8 GB models and 5 colours (depending on capacity), all with a microSD card slot which supports microSD-HC cards. FM radio, and built-in microphone for voice recording.
All at very competitive prices too.
Mathematically Challenged
Don Sherman, a biomedical engineer from Wayne, has been listening to DGW since its inception and enjoys the shtick.
He writes in to challenge the claim that the Desktop Earbuds Speakers 500XL (Episode 528) are 500 times the size of the iPod earbuds. He reckons that the iPod earbuds are about 1 cm in diameter, which means that the XL500 would have to be 500 cm, or 5 m long, which they cannot be.
That's only one dimension. One could of course try to calculate the volume. Let's do some (really rough) calculation.
Let's assume that the earbuds and the speakers are all semi-spheres. The volume of a sphere is 4/3 x π x (radius)³. My iPod earbuds (admittedly the more recent version, not the original ones which the 500XL resemble) are about 1.6cm in diameter, or 0.8cm radius. The 500XL speakers are about 4 inches in diameter (according to Perpetual Kid), i.e. 10.16 cm in diameter, or 5.08 cm radius. The volume ratio between the 500XL speakers and the iPod earbuds is therefore (5.08)³ ÷ (0.8)³ = 256, i.e. only 256 times. In fact, for the 500XL to be 500 times in volume, its speaker diameter will have to be 5 inches.
There is the volume of the "handles" to consider as well, but that still wouldn't push the ratio up from 256 times to 500 times. I think Fred who makes the 500XL may be mathematically challenged, but surely no one is going to mind when he's come up with such a charming idea. At least 256 is a nice binary number!
