5 Exceptional battery lifeviperracer | 14/07/2009 | See all viperracer's reviews (1)Thoroughly pleased with my Acer Timeline. Battery life is exceptional, easily get 8hrs of use when undertaking standard tasks word/email/surfing. The unit is very slim and appears slimmer as it slopes away from the HDMI output and usb points. Integrated card reader, web cam and a great spec for a laptop with plenty of storage. Make sure you update BIOS and drivers due to known issue with processor jumping to 100% which is rectified with update.
