The MSI laptop sold by Office depot 2 weeks back for $450 had great features too. But, MSI did a poor job configuring the hardware and the drivers. That's where HP/ Dell/ Lenovo beat the small guys like Acer and MSI.
There were plenty of problems http://slickdeals.net/forums/showthread.php?t=1633178
Acer is moving fast, and is no longer small. A close 2nd to Dell, behind Dell and HP but above Lenovo in market share. Acer has one advantage in that you can find drivers on the US, Taiwan, and Europe sites.
