The HP Mini 110 comes with a standard set of expansion ports - 3 USB 2.0, Ethernet, Headphone, Microphone, VGA and a 5 in 1 card reader. It is powered by a standard 3 cell battery which provides about 3 hours of battery life with standard usage. You can pump up that figure a little by switching off your Wi-Fi when not in use, lowering volume, lowering display brightness etc. You can also buy a 6 cell battery upgrade for an extra $40.
The HP Mini 110 is a very nice option for those on the lookout for a budget netbook. With the 6 cell battery upgrade, it is one of the best options you have.
