Today, one of our team members completed in just one hour what a supplier had estimated would take 72 hours. Perhaps we didn’t explain it clearly, or the supplier misunderstood. Or maybe something unusual happened along the way.

Connect a keyboard or mouse to your smartphone, tablet, TV box, and other devices, so you can type, navigate, and control your devices more efficiently.
Useful if you need to write big texts, have longer conversations, or just to play games!

Today, my daughter’s citizenship teacher asked the class to write a letter to their future selves - a message they’ll only read two years from now.
Interesting exercise.

Incorrectly, people tend to use simple passwords, often related to personal information, because they are easier to remember.
When using complex passwords, people often end up writing them down somewhere. In these cases, the password can be found relatively easily by others.

At the time I also bought a Magic Mouse, and although I initially liked it and used it for a while, I later felt that it wasn’t the right mouse for me. I ended up selling it this year and getting back half of the value :D
Three years ago, I bought a new computer and, for the first time, I chose an Apple device - a MacBook Pro. Three years later, I have no regrets at all; it was without a doubt the best decision I made.

Did you know you can connect a keyboard and mouse to your smartphone or tablet?
And to the TV box?
This is great for longer texts or extended conversations, or even to play games.
