What to Consider Before Purchasing a Laptop Computer
1. Portability - The main reason to have a laptop or notebook computer is portability - the need to take your entire computer from one place to another. If you don't need portability, then you should probably buy a desktop.
2. Expense - Laptop computers cost almost twice as much as comparably equipped desktops. Shocking isn't it?
You can actually buy two comparably equipped desktops for the price of one laptop. So if you have to have a computer in two separate places, you would be better off with two desktops (if they were reasonably close together you could hook them together in a wired or wireless local area network (LAN).
3. Speed - Laptops are 20-30% slower than a desktop with the same features (CPU, hard drive capacity, etc.). Slower CPUs, motherboards, hard drives, and video systems all contribute to the speed loss.
4. Upgradeability - Laptop computers are mostly non-upgradeable. Whatever CPU, video card (built into the motherboard), sound card (also built-in), and screen, that come with the laptop are the same parts the laptop will end with.
While it is possible to upgrade main memory, and removable drives, the upgrades can cost twice as much as a desktop's. Upgrades using PC cards or docking stations are also very expensive.
You can also upgrade newer laptops through their USB, USB 2.0, and Firewire ports. Only USB 2.0 and Firewire ports can run high speed devices e.g. hard drives and dvd drives. Again, all external drives cost almost twice as much as an internal drive.
