Laptop versus tablet versus desktop

It's been some time since I wrote the last english article about computers.. a few months. I have a good reason to open the subject of what computer shoul I (or you or anyone else) use... it all started with a discussion I had a few days ago with someone.

The first thing to consider when you are buying a new device is its purpose. In the beginning, when the computers first appeared and the next few decades of development, we did not have much choices. The computers became smaller and smaller, from big tools that filled entire rooms, that can not be moved, to personal computers (the PC's) and the portable computers, but they all remaind in the same "range". Their processing power was increasing and their size was getting smaller one year after another... now we have a lot of choices between various desktop and personal computers, laptops and notebooks, tablets and smartphone. We have CPUs and micro controllers in our refrigetators (some of them can order products over the internet), they drive our cars, and if they all would stop working in the same time we would be in biiiig shit. 

If someone would tell me 20 years ago, when I first came in contact with some 286 computers (do you remember them? ) and later with some 386 computers linked into a network (in highschool), that a louzy smartphone will have the processing power of all the computers of that network encapsuled in a device that fits a blue-geans pocket I would have laught.

The tendency is to mobile devices, but the old fashion PCs are still an (important) part of what people want. That's why there is still a question about what should someone choose when purchasing something. The first thing to consider when you are buying a new device is its purpose. Yes, I know, I've said it before. But it's too important not to repeat it bolder.

If you want something to check emails or to browse the internet, or to tweet and to stay in contact with friends and other people on facebook you don't care what you get. A smartphone or a tablet does the job just great.

When you need more processing power, something that the smartphones and tablets can't give you (yet!), for example when you are trying to manipulate some images, videos or to render some 3D graphics, then you'll need a biger device. If you really need your mobility you can try a notebook or a laptop - they can do that in some degree. But for some projects, when you need the results fast and that require a great number of calculation, you have to "return" to the fixed old fashion (only in matter of mobility) computers. It does not matter if it's a PC or some kind of graphic server, the result is the same.

My advice is to combine all these. You can get a computer for whatever you need (or want) to do at home or at the office, but get a mobile device (everyone have a smartphone, right) to remotely connect to your computer when you need to give it instruction about your projects. In the world where your refrigetator can order products over the internet when it feels it's empty or the cars (almost) drive themselves it should not be a problem to connect to other computer or device (almost) anywhere in the world. Right?
