That laptop hasn't slowed down. Society has just moved on.

And I'm glad I had it. I was able to get a lot of use out of it. And there will be times I need to be mobile so it'll still see use.
I the computer I'm using now is 5th generation but I'll have to check. But I think that matters less than the overall number of cores and clock speed. And yes, thankfully, it has an SSD. It came with a tiny one - 64 GB but I upgraded it to 500 GB years ago.
I still have 4 x 2 TB SATA drivers that I was using in a RAID 10 configuration. I'm going to try hooking them up again just to see what's on them. They were just used for data. I don't think the much slower SATA speed matters when you're not running applications on it. And those are run on the SDD.
Ubuntu looked really good but there were a couple of issues with it. I loaded it mainly just to make sure the computer was working okay because I needed Windows 10 pre-installed on it so it was wiped pretty fast. Sorry, Fox! I still think Ubuntu looks great and it worked fine except for the glitches I came across. I just wasn't all that motivated to fix them.
And, I wanted to check out Plasma again because I've been stuck on Xfce for 2 years. I remembered that MX Linux has a Plasma edition. So now the computer has that and Windows 10 (for games and educational purposes).
I haven't given up on Ubuntu but decided I just wanted, for now, to run with what I knew so there'd be less fuss.
