it's obvious that laptops are going to get more awesome because of this
I remember reading that standard laptop batteries use cylindrical batteries in a block closure, meaning that the added cost of manufacturing them as blocks isn't worth the value users would get from an extra 50% battery life. I think cheaper manufacturing is what's key for laptops.
Block battery's reduce from factor, but they don't change the weight. If you want 50% more battery you end up with a ~50% heaver battery. Which is great for cellphones but laptop's are more limited by weight than volume.
