I agree. That was one of the biggest factors when I made my decision to buy the mini 9.
I feel like the more disk space you have, the less you seek to optimize its use. I keep trying installing softwares that I don't really need, but think they are cool. And a year later, I finally realize it is useless and start uninstalling it. Same goes with MP3s and videos.
It's only a netbook. The maximum I would need probably is 16GB including system files. I use my desktop or laptop that are much more powerful than the netbook. And, if I really needed to save something big, I could just use my external HDD.
Also, if it's this small, you would want to carry it around everywhere. That increases the chance of you dropping it. I'd rather have a SSD
than HDD just for that.
