I need to replace my 705, which I recently lost (@#%^ mount!), so am looking at either another 705 or the newer 800. The one thing that I read in another forum that bothers me about the 800 is that the screen is supposedly dim and you have to have the backlight on much of the time, which drains the battery.
With my 705, I pretty much just used it for displaying multiple data fields and I don't recall ever needing a backlight except for a couple of early morning rides. Is the 800 that much different? I'd hate to have a screen that washes out in sunlight like my cell phone does!
The other interesting difference in shopping around is that it looks like I can get an 800 cheaper than a 705, even though the 705 is "obsolete" from Garmin's viewpoint. What's up with that? I only need the basic unit since I still have my HRM strap and cadence sensors.
One other question: can the 800 still hold 8 data fields on the screen at once?
