I need a laptop for when the family go on vacation every winter. I ended up buying a 27" iMac in July since our two PCs were having "issues". Anyway, I still need to buy that laptop; I need some input about which one would be best for our needs. I am looking at the 13" and 15" specifically. The 13" would be best for portability, but the 15" can be used as a desktop to replace the oldest of the PCs. It would be used for internet games and browsing, nothing really intensive. I don't like the idea of buying out-going technology, so the i5 is more appealling. Which would be the greater inconvenience?: Having to carry around a larger/heavier laptop, or having a smaller, possibly under-powered laptop at home? I know a lot of this is personal choice, but I would appreciate the insight of those who have had the same sort of dilemma.
