Yeah, that was my first impression, too. I expected it to be huge, but here's its size in comparison with a couple of Solus VMs:
Having just started this exploration, the only things I've added to it are Thunderbird and Vivaldi, and I've removed nothing yet ... not even Firefox. It's by far the most colorful distro I've ever encountered, to the point of distraction. I suppose a more subtle theme might fix that, but I haven't gotten that far into it yet.
And, of course, that might be the version I installed. I just picked the first in a long list of options.
There was one interesting feature that I noticed. Apparently the .ISO installed a BIOS version by default, but while I was looking through the settings, I noticed an option that read something like "Change to UEFI." I did that, and after a reboot there was a considerable increase in performance. I was really surprised at how much of a difference it made. I'd never seen anything like that in another distro.
