Actually, we had a good reason behind it. He's suggesting that, if possible, get the most you can. Because it's a primary computer. Will he need it all? Maybe not, but he has the option to later on down the road. It's not necessarily superfluous. Get the best you can afford within reason. I happened to get a base line MBA but upgraded the SSD. And it's lovely not having to worry about internal storage.
Yes, of course nicer things are nicer.
I've seen a lot of posts from a lot of people on these forums that come down to, "if you can afford it, why NOT buy [the product or upgrade in question]?!"
I find this sort of advice depressing because I know people who do spend whatever money they currently have on whatever thing they're currently buying, be it a car, house, laptop, etc. They end up with nice things but they save very little money and are often stressed out about their finances and are miserable.
I think if more people made purchasing decisions according to their needs vs. what they can afford, they'd lead happier lives.
Like I said before, there are definitely legitimate reasons why one might NEED more than 128GB of internal storage, but I imagine the vast majority of people don't. It's very easy to get a small external drive with huge storage capacity and use it to store infrequently-used files.
I suspect a lot of cases of people posting to this thread saying they
need at least 500GB (or whatever huge amount) of storage are really cases of people not being aware of what's taking up space on their drive--I bet that if they ran a utility like Disk Inventory X, they would find that a lot of space was being taken up by files they don't need, don't want, didn't realize they still had, etc. etc.
