Good post Carlos,
Just to expound on expansion slots a bit more, I think the reason many companies & organizations use Dell is due to their customizability (if that’s a word). While I definitely have my preferences when it comes to manufacturers, you cannot find many models with the number of replaceable components & expansion capabilities that Dell provides. Many manufacturers hardwire most their components to keep you buying new laptops every few years, while i feel like Dell does a good job at trying to keep things interchangeable as possible. This has been my experience but I am curious if anyone else has an opinion on this?
