I've been using a T410 for almost 6 years now. It's got 8GB of RAM, an SSD and the hard drive that it shipped with is now in the ultrabay. With the 9 cell battery I get almost 5 hours of battery life with normal use. I see no reason to upgrade. Sure a newer laptop might be a little thinner or a little faster, but for what I do I'd never notice. It's not like an ultrabook is going to fit in my pocket. I'd still need to carry it in a bag.
