Though Intel Core 2 Solo SU3500 processor will be quite slower as compared to a Core 2 Duo that you find commonly in laptops now, it is also designed for consuming very less power. That's why you get 7-8 hours of battery life with it. Acer timeline series is not meant for heavy-duty work like graphics designing/video editing (though it might be able to handle this). For normal tasks like office applications, internet, movies there should not be any performance issues. So, if you want a moderately powered laptop that is highly portable and has very good battery life, you can go for this. If you want powerful laptop, you may check one with Core2Duo processor.
