Glad to hear your hubby is doing OK Wynona.
I'm still debating about doing the upgrade on my Windows 7 desktop machine. That one is getting a bit long in the tooth now, it came with Vista installed and when 7 came out I bought that when it was on offer. At first I dual booted between Vista and 7 but then got rid of Vista and clean installed 7. The only problem is that it only has a 250 GB drive and 2GB RAM.
I will upgrade this Asus which came with 8 and was then upgraded to 8.1, this one has a 320 GB drive and came with 4GB RAM but I put another 4GB stick in to take it to 8GB.
It's the machine I'm using to test out 10 but in a VM not as the main OS.
The hard drive is plenty big for (probably) whatever you want to do. I have my laptops with 500 GB hard drives (both partitioned to a little less than 250 GB) to take Windows 10 as a dual boot.
