Amongst the two design 'problems' which may have been addressed in the 10-speed version are:
- lack of back lighting (which is what I think you are referring to)
- lack of a capacitor or flash memory or whatever which will allow the computer head to retain the stored data
Now, what I have found is that back lighting looks good on paper, but is probably not meaningful unless you are planning on doing a lot of riding at night. This may be stating the obvious, but using the back light will shorten the battery's life. An auxiliary headlamp on your helmet will probably be a better way to light up the display.
The second issue can be more relevant because it seems that the battery usually dies when you aren't looking (
e.g., in the middle of the week!) ... the end user has something between 3-and-5 minutes to change the battery after it dies ... there is a "low battery" indicator; but, I don't know how long it is displayed (
NOT long enough).
BOTH issues were addressed in the Campagnolo ErgoBrain which I vaguely recall was introduced
after the Flight Deck (
again, both are made by Cateye); so, I can only hope-or-presume that the 10-speed variant of the Flight Deck has back lighting + is capable of retaining data ...
BUT, someone else will have to clarify whether or not the more recent 10-speed Flight Deck computer heads incorporated back lighting & data retention.
BTW. The wireless harness is an idea that looks good on paper, but you will be paying a premium for the nuisance of having the unit not function when the computer head's battery is merely a little weak (
but, far from dead) ... it wasn't until I
tested a failing computer head in a hard-wire harness AND then swapped the computer head from the hard-wire harness to the wireless unit that I was able to come to
that conclusion ...
- in retrospect, it's possibly a-good-thing to have the computer head become hinky in a wireless harness when the battery is weak because it is an unintended "early warning system" which will give you the opportunity to quickly change the battery without losing the stored data, BUT it is nonetheless an annoyance if you don't have a spare battery handy
