I had good luck with an old Acer-Windows XP. My current Dell-Windows7 i7 is still going strong after about 7 years. I did replace the hard drive from a 5400 RPM to 7200 RPM after about a year, and I noted a significant improvement in loading and running programs.
Before the Dell, I bought a Samsung-Windows7 i7. It lasted one month after the warranty expired. I tried to get it fixed locally. The local computer shop tried to get a new motherboard, as that was were the problem was. They were told Samsung didn’t make replacement motherboards for that model. Thus, I have an $800 door-stop and I will never buy anything from Samsung again. [My Samsung DVR died after only 2 years of use.]
I also have Toshiba Linux Mint i3. It is okay, but somewhat sluggish.
I have an RCA android tablet that is nearly junk. It takes forever to reboot after it shuts itself off frequently.
I have a Win10 tablet that has similar problems. Sometimes, it reboots 2-3 times in a single day. I find Win10 frustrating anyway, so I usually stick with the Dell Win-7 laptop and Gateway Win-7 i5 desktop.
I have a Samsung Galaxy TabPro S 12 inch. Been using it for years with no problems. I bought 4 store demo units, like new..traded one for an brand new Samsung Galaxy phone plus $180 cash, still have 3 of them.
Windows 10 Pro 64 bit, 4 GB ram, Intel core m3-6y30 1.51 GHz CPU, SSD. I use it as Tablet mostly but has a decent keyboard touchpad to use as laptop.
I have had Acer, Asus, HP, Toshiba laptops, all had problems and are either unfixable or too expensive to fix.
