Not sure about iPod but many players like the cowon iaudio or sandisk sansa series act just like USB drives. So you just drag and drop songs to or from any computer so its easy to share songs with friends.
"To get GS to make the site look less official/confusing and bit less insulting" is only part of the answer.
The other part, as mechanical_fish has elqouently pointed out above, is to reach present/past/potential customers of 37s who were mislead by GS into thinking that 37s does not answer customer questions. Contacting GS alone would not have solved the damage GS already did. It was not enough for 37s to prevent future abuse, but also to turn back the damage already done in the past.
They are also offering a browser plugin for your PC or Mac so you don't need their box. The box is only required if you want to use your TV and not your computer.
I strongly believe that these things are not trivial to do well yourself and maintaining such an infrastructure will distract you from your core competency.
Don't tell that to us here. Say that in a convincing manner on the homepage.
You will note it includes no standard benchmarks and only includes a vague hand-waving claim saying that its orders of magnitude faster. No real world numbers are quoted. Nothing is said about how good the CPU implementation was and so on.
After working in GPGPU for a while, I have become really wary of vendor claims. Vendors do all sort of tricks to make their claims look good : comparing against single core non-optimized CPU code, comparing different algorithms on GPU and CPU, not reporting the time required to transfer data between CPU and GPU, comparing only 32-bit float performance when 64-bit floats should be used and so forth.
Of course, GPUs are certainly very good for some types of problems. But they are not magical solutions and are not suitable for most problems.
Its a little funny though. I learnt programming first and maths later. SO when I encountered functions in maths at school, I thought "oh I already know this stuff".
