Acer isn't exactly known for brilliant power engineering, so a better vendor could likely do better. But this also wasn't exactly a high-powered chip, either. So this is probably a plausible baseline for battery usage in Win 7.
They need to beat this by quite a bit in Win 8, or the tablets will be a tough sell.
