Oh yes, a very elegant solution!
That's not making it short, that's making it fat.
Twist-tying 3 cables connected to a tiny ext-connector... that's like three overweight people occupying seats 36A, 36B and 36D of an aeroplane!
I'm sorry, I can't tell if you're being sarcastic or not. Because seriously, no it isn't, not even close. I'm not even entirely certain what analogy you're trying to pull off here. Heavy cables pulling out the ext connector?
It's really not difficult. The EXT connector is small. If you twist and tie the cables to make them 'shorter' you're going to make them 'fatter'. You're going to end up with three chubbies bunched up together at the end of your connector. It still requires more space in a carry bag to transport than a simple connector with three female sockets on the end. If I'm going somewhere with my Pandora that already has SVideo and RCA cables (which is pretty much everywhere I go) then it's wasted space.
And if one of the cables gets damaged (yes I'll openly admit I'm not as careful with cables as I should be) you will be required to cut the cable and solder on a new one. If a SVideo or phono cable (which came bundled with a more standard 3-female TV breakout cable) gets damaged, then it's simply a case of replacing the cable, or reusing one of the many cables I have lying around my house (many of which are much longer, even, than 10ft).
Plus there's the issue of extending the cables. If I want to extend the cables I'd need to either buy a double-female adapter for each cable so I can use my existing cables, or buy brand new female-male extension cables. Not a biggie, I agree. I have the adapters lying around for the audio side of things, and an S-Video adapter would be pretty easy to come by. But it seems a bit of a waste when I have 20 and 30ft cables lying around already.
At the end of the day I've had quite a few devices with TV breakout cables. Every single one of them have come as tiny little leads or boxes with female connectors for composite/SVideo, and L/R audio signals so that consumers can use their choice of leads. From cameras to PDAs to PC TV adapters and GP2Xs, it's the standard that companies adhere to. Yes, part of that will be to cut costs. But it also offers the consumer the choice of cabling. Probably saves the company quite a bit in warranty claims as well.
Clearly, for most people on this forum, who want the cable for connecting to their equipment at home, a 10ft lead is a good thing. That's easy to tell from the responses so far. But for people who may want to hook their Pandoras up to, for example, on-site projection equipment, it's a bit of a pain. Especially as you have to worry about what to do if the cable gets damaged (carry a spare TV-out cable).
So I concur that popular opinion says a long lead is good. But saying there's no advantage to a standard breakout cable is just not true.
