Laptops are perfect for portable use and limited daily use. But if you intend to use the laptop for long periods of time everyday, then you need to be aware of the design differences.
Laptops have limited cooling abilities due to the compact design and limited airflow inside the case. The result is that most laptops run hot, which can affect the life of the components inside a laptop. And as previously mentioned, it is not easy or cheap to replace laptop components.
I used a laptop keyboard daily for 3 years and many of the letters were worn off the keys. When you wear out a keyboard on your desktop, you go out and buy a newer and better one. When you wear out your keyboard on your laptop, you go out and buy a new and better laptop.
If you intend to replace a desktop home computer with a laptop, then I highly recommend a laptop with a docking station. A docking station allows you to use a desktop monitor, keyboard and mouse, which saves you wear and tear on your latop...not to mention the possibility of a full size keyboard, larger monitor and more ergonomic mouse.
Ignore the posts that claim a laptop is faster than a desktop, that can only be true if you compare apples to oranges. A fast processor and video card produces a ton of heat, which requires multiple fans and good airflow even for a desktop system. A laptop is not designed to consume the power and provide the cooling that is required of high performance processors and video cards. Laptops have improved immensely, but for the same amount of money you can always find a faster desktop.
- If you want speed, performance and the ability to upgrade a PC for many years, then a desktop is your best solution.
- If you want portability then a laptop is your best solution.
- If you can't decide or want both, then consider buying a good desktop and a cheap netbook. Netbooks give you portability at a great price point, and they will handle what most people want to do remotely (Surf internet, read email, watch movies).
