I run Tiny Core on 3 partitions. One for this version, one for the next version, and one for experimenting. Sometimes while experimenting, something has not worked. I can boot from another partition and fix the problem. I have always had a working version on one of the partitions.
3 partitions are not necessary for most people, but 2 would be handy for many people. Tiny Core does not take up a lot of space, so you don't need huge partitions.
I have mentioned before, I use computers that other people discard. Why spend money when you can get them free?
About 4 or 5 years ago, I picked up a 667 mhz computer with 512 mb of ram, and used that for the internet.
I tried other computers for a while, including an 800 mhz computer (which I replaced the power supply from another free computer), and a 1.5 ghz computer with 256 mb of ram. The ram is a very unusual type, so I couldn't increase it.
I recently picked up a 1.6 ghz computer with normal ram slots. This had the ram, hard drive and dvd drive removed. I put in 1 gb of ram. This performed well browsing the internet.
I then picked up a 1 gb ram sim, discarded in a computer which was not working. I sometimes get parts from computers which are not working, such as ram, hard drives, dvd writers, etc. I have recently picked up 80 gb and 60 gb hard drives from computers which were not working.
For a while I ran 1.5 gb of ram in the 1.6 ghz computer.
Since then I picked up a 2.4 ghz computer, which was discarded complete and working, with 512 mb of ram, a 40 gb hard drive, 2 dvd drives - a dvd reader and dvd writer. This was running slow, as it needed Windows reinstalling (it is sad that some people don't know reinstalling Windows will fix it, so they throw the computer away). I put in the 1.5 gb of ram, the 80 gb hard drive for Tiny Core and maybe other distros, and the 60 gb hard drive for backup.
I have sometimes given computers to people who are not so well off. Computers are becoming so inexpensive now, that even some of these people may not want older computers.
As computers become less expensive, higher performance computers are being discarded.
Anyone living in affluent countries, thousands of used computers are being discarded in your community each year. It is just a matter of how you can get hold of them.
Be aware, some people are selling old slow computers for almost the same prices as new computers. Don't pay those prices for them.
If you don't know how to replace a hard drive or ram, using free computers is a good place to learn. If it didn't cost you anything, it won't matter if you break it.
In poor countries the opportunities are not the same.
I should mention, I have bought computers. I have a notebook I bought for portability. I bought a computer which I set up for television. The best television system these days it a computer with a tv tuner. You can get a video card that will output to tv. You can record to hard drive. Most things you delete after watching them. Anything good, you can save to dvd (or blue ray).
