Battery life should be in reviews so I'd check that again.

There's a huge issue with battery times for new laptop buyers. I have seen a lot of models that range from 1 to 10 hours of run time depending on use. This means that only the newest of the new try to game on battery power. They learn fast why.

As to trackpads, all are pretty useless except when I don't carry a mouse. The most important feature I use is the off setting. I must be able to turn it off.

As to keyboard, that's highly personal. Go to the stores and test them out.
