1. I love the color blue, and blue light in general, but I have a strong dislike for blue LEDs on devices, because manufacturers tend to slap one or more in and consider their job done, with no thought to how much light comes out - my cablemodem has two blue LEDs that would singlehandedly light up my living room at night, had I not taken countermeasures. You don't want to just completely black them out with electrical tape, because you actually do want to know what they're saying, but they're difficult to mask effectively so that one gets the information they can provide without also getting room-alterating illumination. Also, one should not have to modify brand-new devices this way. I see them too often as a clear sign that a manufacturer doesn't care to do things right, they're just trying to cheaply hit their list of required bullet points. Blue LEDs on equipment are all too often like that one friend who doesn't have an inside voice, and can only COMMUNICATE BY SHOUTING.
2, 3, 4. Anything _not_ running Windows, Candy Crush, or Flash is a huge win. The only good use of Flash ever was HomeStarRunner and StrongBad.
5. Kitten videos are entertaining. I don't need a lot of them. But I am highly suspicious of people who do not both understand and like cats.
6. Biometrics are handy if they ACTUALLY WORK. Apple's TouchID works. Most of what came before was worse than useless. Still remember my brother spending minutes and minutes trying to get the gimmicky biometric reader on his laptop to recognize him, every time he opened it.
7. Eh, don't want a piezo speaker, but the Pi would be ever so much better if you could plug in a basic old-school two-wire 8-ohm speaker and get useful sound out of it - not hi-fidelity digital audio, just what an Apple II was capable of doing 40 years ago.
8. 64 GB of RAM - I'll never argue against more resources, if they are free or nearly so. If more RAM doesn't make the system way more expensive, slow, hot, or power hungry, bring it on. With that kind of RAM, the first thing I'd do is hide the SD card behind an equivalent sized ramdisk using overlayfs, unionfs, or some such. Then you could only write out changes to the SD card every once-in-a-while instead of constantly, and make the card last much longer (yes, you'd also need a few seconds of warning before the system powered down - supercapacitors, anyone?).
9. FireWire is a terrific standard that has lost relevancy. The FW400 connector was a thing of beauty and back in the day FW400 was SO much better than USB for pushing disk-sized data through.
10. I still recall RMS joking at a conference that they were having trouble finding volunteers to work on GNU Cobol.
