do you prefer to choose desktop computer/notebook(laptop)  

i prefer a laptop . coz is convenient :)

I choose PC, i know its not efficient and portable. You can only use it at one place.
But the hardware is cheaper, and i think its simple if we want to upgrade it.
Just open the case then plug it (^_^)

Laptop computers and desktop computers both have their own strengths and weaknesses. The major strength of a laptop is mobility and it is best suited for road warriors. With a laptop computer, you can go wherever and it will be with you, giving you access to your information all the time. One drawback with a laptop though is the processing speed and power. Few laptops can compare to desktop computers with regards to speed. And not unless you carry a very long extension cord, your computing experience with a laptop is also limited to its battery capacity, which usually last for 2 to 3 hours.

As for desktop computers, they are more powerful as compared to laptop computers. They have higher processors, larger hard drives, and larger memory. Screen display is also another major function. And desktop computers can always be turned on without having to consider its power requirements. As such, the only drawback I can see with desktop computers is being portable and mobile. You are limited to one location when you are using a desktop computer, probably in your home or office.

Between the two, I would prefer a laptop. I don't need all the bells and whistles of a full blown computer. Just to be able to get access to my data wherever and whenever is enough for me. :)
