This quickly became my favorite computer.  The backlit keyboard is very pleasant and useful for my needs while the backlight times out after a reasonable time when it is not in use.  I have owned and used seemingly countless computers, and this is the most pleasant of all to use and carry.  Battery life is excellent for my needs, but for convenience, I have it set up to keep everything running when it is operating on external power.  It doesn't have a separate numeric keypad, but that isn't a significant issue for my needs.
