HP has unveiled a new business-focused netbook today, the Mini 5101, as well as a new member to its ProBook family of laptops launched earlier this year. The first is the successor to the Mini 2140, which is currently being phased out, and comes sporting some slightly bumped specs along with a 95-percent chiclet keyboard that is reportedly spill-resistant and a slick aluminum and magnesium housing.

The HP Mini 5101 has a 10.1-inch matte display that comes either in 1024 x 600 or 16:9 HD resolutions (1366 x 768). It is powered by a 1.66GHz N280 Atom processor, 1 or 2GB of 533MHz DDR2 memory, and will include a 160GB fast-performing 7,200RPM hard drive as standard with the unit. Additional storage options include 250GB and 320GB HDDs as well as 80GB and 128GB SSDs; and OS options include Windows XP Home, XP Pro, Vista Home Basic, Vista Business, or SUSE Linux Enterprise Desktop 11.

A 2-megapixel webcam is built-in along with three USB ports, Wi-Fi, VGA out, headphone jack, and an RJ45 port. There will also be 4-cell and 6-cell battery options, for up to 4.5 or 8 hours of use respectively, according to HP. The 5101 is reasonably lightweight at less than 3 pounds and will be available next month starting at $449.

As for the HP ProBook 4310s, it shares the same basic design and styling as current models in the series, but comes with a smaller 13.3-inch display. It is built around Intel Core 2 Duo processors up to 2.8GHz, and ships with up to 4GB memory, hard drive options up to 500GB, and the usual range of connectivity options. The ProBook 4310s should also arrive this July, with a starting price of $799.
