I volunteer for a charity that helps people to be more confident with IT. I use my laptops to train with and because Windows laptops are so common, I bought one so that I could ensure I was comfortable with it as well as my Apple machines. I have a preference for Apple and I'm using my iPad to type this. However, I believe most people think Apple expensive and the perception is they are difficult to switch to if you are used to Windows.
I would say that you can use a laptop anywhere but a desktop tends to be set aside in a separate room and you can be more social using a laptop. If you use a Windows desktop computer, then follow that with a Windows laptop, you shouldn't find it very different. I think it's a good idea to try and get used to a touchpad or even a touch screen if you go for a laptop with one - I've never used a laptop with a touch screen though, I'm not sure it's necessary. Using a mouse on your lap is a nuisance and means you need a work surface of some kind. You should try different laptops before you buy. Look for screen clarity, is the size comfortable for you? Feel the weight, type using the keys - are they clunky? Make sure you adjust your touchpad to your touch before deciding you can't live with it.
My main advice though is, when you get someone to set up any computer for you, ensure you understand exactly what they have done. If you want to use your new laptop with your desktop, you may have to either give some of your current passwords to someone else or be there to enter them yourself. Make a concise note of passwords and what they are for. All my newer machines have a set-up menu to work through, it's not as difficult as you may think. So often I find that people have machines set up for them and they don't know how to make changes and, when something goes wrong as it must, have no idea where to start, and keep entering the wrong password. I don't believe you can set up any computer without a minimum of 3 passwords. These are
- a user name and password to access your new machine or, for Windows, you will probably need a Microsoft Drive password although you may already have one for use on a Windows desktop
- a WiFi password from your router
- your existing email account password and details.
Although, if you have fingerprint recognition built in to your new laptop, perhaps you will need fewer (yet another consideration).
I hope this hasn't put you off. There is lots of help online.
