From yesterday: Like the Duke Blue Devils against Villanova, the MSI Wind U120 couldn’t stand the second-half rush of the Dell Inspiron Mini 9, which carried away the win, 65 to 35 percent. Is Dell the Big East of the netbook tournament? If both the Mini 9 and the Mini 10 win their next games, there will be two Dells among the final four. Or is it ASUS, which still has three mini-notebooks in the tourney? Which brings us to today’s game: The powerhouse ASUS N10J-A2 versus the 10-inch Acer Aspire One. The newer of the two, the $349 Acer Aspire One AOD150 is a nice step up from the company’s earlier 8.9-inch model. The screen is a comfortable 10 inches, the trackpad is larger and much improved, and it has a sleek, dark blue finish. Like the Knicks’ Al Harrington against Sacramento (twice), Acer was charged a technical; as we noted in our review, the first battery that was sent to us was a six-cell 5800-mAh battery, which lasted an unheard-of 8 hours. We soon discovered that only a few of the new Aspire Ones would have this, and most would come with a 4400-mAh battery. Once we received the new battery, we found it had a runtime of 6 hours, which is still 20 minutes longer than the six-cell average for netbooks. As befitting a company with a gazillion netbook SKUs, ASUS last year introduced the N10J, a netbook with switchable graphics. We reviewed two models, the N10Jc, and the N10J-A2, which costs $799, but has Vista, 2GB of RAM, and a 320GB hard drive. Rare for a netbook, the N10J sports an HDMI port, in addition to three USB, VGA, an 8-in-1 memory card reader, and an ExpressCard slot. It also sports ExpressGate, ASUS’ instant-on environment, as well as SmartLogon face-detection software. Using its integrated graphics, the N10J performs pretty much like other netbooks, and we were able to get 4 hours and 36 minutes out of its battery. Switching to its Nvidia GeForce 9300M GS graphics card only knocked off about 20 minutes of runtime, but pushed its performance into the range of ultraportables. So which will it be? The snazzy, long-lasting Acer Aspire One, or the more-than-twice as expensive Asus N10J-A2 with its switchable graphics and a plethora of ports? Voting is now closed – The Asus N10J-A2 wins. Stay tuned for our next matchup, the Lenovo S10e vs. the Samsung NC10.
