I have a Samsung N150 that has similar specs and it has limited uses, but they still exist.
CPU: Intel Atom N450 1.66GHz 1/2 core/thread
Memory: 2GB DDR2-667
SSD: Crucial MX100 256GB SATA
OS: Windows 10 Home 64-bit
It originally had a regular old 250GB SATA hard drive, but I figured an SSD couldn't hurt. Well, it didn't hurt, but it didn't help much either. I don't know WHY it's still as slow trying to access files on the system, but it is. But benchmarks show SATAII speeds (~240MB/s reads).
It originally had 1 GB. But even with Windows XP that's simply not enough. So it got upgraded within a month of my purchase in 2009.
It originally had Windows 7 Starter (32-bit). After the SSD upgrade and during the free Windows 10 upgrade period, I cloned the HHD to the SSD, then upgraded Windows, then wiped the drive and did a clean install with 64-bit.
Brightness controls don't work within the Windows interface, but the keyboard buttons DO work thanks to a registry work-around I researched. But plugging in the AC adapter won't suddenly shift the screen to full brightness like it did with Windows 7. You have to manually key the changes in.
This is also the ONLY computer I have with Windows 10 on it where automatic updates are a problem. Because of the nature of the single-core ATOM, background updates bring the whole PC to a virtual grinding halt almost every time I turn it on and am connected to the internet in some way. Once the system has been allowed to fully update, eventually the CPU usage will drop from 99% to fluxuate around 15% and you can suddenly do something with the system other than wait.
I used the system for taking notes in college classes. It's actually WONDERFUL for this purpose. Plenty of storage, enough screen size to be useful and small enough to fit into even cramped bookbags. I wouldn't run Microsoft Office, though. I run LibreOffice or the like. They're smaller and more streamlined for use on a system with limited resources.
Granted, I've gone over the system with a fine-toothed comb in order to trim otherwise unnecessary processes down. I used to use Google Chrome, as it was lighter than IE. Now... even Chrome is heavy on system resources compared to Edge. Hate to say it, but with Windows 10, Edge is pretty much the only web browser that works decently now.
The 1.6 GHz on the CPU doesn't even really bother me. It's the fact that it only has ONE CORE that bothers me. If I could somehow swap out the CPU in this system for one of the much newer quad-core ATOMs. Hell, even the dual-core N570 would have been nicer for anything Post-XP.
