Why should you stop using a Raspberry Pi for everything?
To use the Pi as a full desktop computer, even with the latest model 3, is a nightmare. To begin with, it operates Linux, which has a steep hill to climb and is not recommended for beginners. Linux zealots believe that this year will be the year when Linux finally makes it to the desktop of the average user, but it never has and never will. Even with the new model's performance improvement, you'll still struggle to do routine chores. The minuscule delay between pressing a key and seeing it show on the screen will ultimately get to you.
How can I make my Raspberry Pi more powerful?
One thing to keep in mind while setting up a Raspberry Pi system is to use a dependable power supply. This should ideally be linked to a power supply adapter with a capacity of 2.5A. After you've figured out your power requirements, you'll want to install a distribution that consumes as few resources as possible. Getting the most out of your Raspberry Pi requires keeping things simple, and various Linux distributions have been created with this in mind. If you need an internet browser on your Raspberry Pi, you're probably already using Chromium, Vivaldi, or one of the lighter alternatives.
Is it safe to leave a Raspberry Pi on all the time?
Because Raspberry Pis are built to work for lengthy periods of time, you can leave them on all the time. It is, however, not advised to do so. The item will overheat and be destroyed if kept on for an extended period of time without sufficient cooling. Its lifespan is also shortened if it is left on all the time. If you want to keep your Raspberry Pi on all the while and not risk damaging it, you'll need to use a linear power source. DC adapters or any decent quality battery supply must be used to regulate this.
