Beyond the frippery of looks and features, you should encounter no qualms with how the 6935G performs. In PC Mark Vantage it compares very well to both the HP Pavilion dv7-1000ea and the Dell Studio 15, mainly due to the boost provided by that faster 7,200rpm hard drive. This is reflected most in the in the Music, Gaming and HDD tests and though our in-house tests showed the Studio 15 pulling out a small advantage, this line has since been updated to use the exact same processor as found in the 6935G.
Battery life, on the other hand, isn't a strong point. In the productivity segment of MobileMark 2007 the 6935G managed a below-par two hours and 28 minutes and it didn't even manage more than three hours in the lower intensity reader test. Both these results fall well below either the 17in HP or the Dell Studio 15, though the Acer does claw things back somewhat in the DVD playback test with a result just under two hours, only four minutes less than the HP.
You should be able to play some games at reasonable settings as well. In TrackMania Nations Forever it manages to produce frame rates in the mid-thirties at medium detail settings, so you should be ok with most titles provided you disable any anti-aliasing and post processing effects.
All told we can find very few reasons not to recommend the 6935G. It might lack the elegance of offerings from Dell or HP, but the basic specification and design are strong and the feature set is superb given the sub-£1,000 price point. This makes it ideal as an all-round desktop replacement that won't completely dominate the room, as an 18.4in does, as well as providing some level of portability so you can enjoy your entertainment anywhere in the home.
Acer's Aspire 6935G does all the things you could demand of an entertainment notebook at a very attractive price, making this one of the sounder purchases one can make this Christmas.
