You charge your phone every 12 – 18 months. A good computer can last for years and part of that means being able to update things. You can only upgrade but so much but every little bit helps make you feel good.

Aspare battery is needed if you are going nto
the field, you never know if you can plug in or not.

Murphy’s Law says your battery will crap out
while doing important wrok…and no AC is available

In this way no need of a big platic case and no problem for the color of it when you have the choice beetween Black and White Netbook or beetween “iPhone rainbow color covers”

Remember an Asus 900 and 900A has not the same battery….

For instance, I wouldn’t buy a computer with a nonremovable battery, but not because “I’d rather use a second battery when I need more juice”, which is the reason given in the ‘no’ option. I wouldn’t get such a computer because batteries deteriorate, and I tend to keep a computer for a long time. Hence I haven’t responded to the questionnaire.

If you post questionnaire type questions, you have to think very carefully about what responding to an option entails for the resondant, and what conclusions can legitimately be drawn.

I would probably be replacing my netbook before the end of the battery’s useful life, although I would be concerned about the resale value I could achive for the unit.

Do you have external chargers?

My Fujitsu 7120 has two batteries, one in the slot that can run a DVD. I prefer to have the two batteries to having a removable disk, as I get around 6 hours with the combined batteries, but I don’t have any way of charging a battery that’s not installed in my computer.

As far as removable vs non removable, I really don’t like the idea of a non removable battery, because I’ve got at least one old laptop that I find useful to have sitting wired beside the couch. It runs with no battery installed because if I put the battery in it, the battery will not charge at all and the computer will not run. This machine is not worth spending money on a new battery.
