The device may be able to accurately predict winning lottery numbers and calculate pi to the 30th digit, but if you can't read the display while on a bumpy trail, it's useless. Many computers display the most important information in a large space, with less frequently used data in smaller regions. This works well, until the cyclist happens to need one of those small bits of data, at which point the rider is relegated to bending over and squinting at the display. I've found that a backlit display is a godsend at night, which is when I spend a lot of my time on my road bike. Without backlighting the low-contrast LCD displays become invisible, requiring frequent stops under streetlights for readings.
Some units allow for removal of the computing device from the handlebar-mounting bracket.
Removable computers can be taken off to prevent rain damage while on a roof rack, and for storage to prevent damage in transit. On the downside, they are more prone to fall off or be stolen.
