When asking the question which is better to buy a tower/workstation or a laptop the question used to come down to the size of your wallet. For a long time PC towers were simply cheaper than a laptop to buy. Normally half the price for the same specifications.
This is now no longer the case as the price of a laptop is now comparable to that of a tower. So now cost is no longer the main issue lets consider the advantages/disadvantages each type of system has.
In the case of the laptop the first most obvious advantage its portability. Designed not only to be easily chucked into a bag and carried to where-ever to want to work or play, but also by having its own internal power source it means you not limited to one place. With the advent of wireless broadband your not even limited by needing a fixed line connection any more. You can take it camping, work in bed, take it to the office, anywhere. However this size and portability is also a limiting factor. Most display screens on laptops are around 15 inches, some go up to 17 in. but anymore than this and the laptop loses its advantage in portability. Laptops also lack space for large internal fans or other mechanisms to cool of the main CPU. Some manufacturers have tried to overcome this limitation by inventing the dual core CPU (a bit like having two carburetors in a car), soon no doubt we will seen quad core and more. Hence laptops CPU's are more likely to experience failure due to over heating.
Towers on the other hand are fixed to a single workplace unless you get some sick joy out of lugging wires and equipment from one place to another and figuring out where every connection goes. This fixed location though does have some advantages, your display screen can be the size you want. You can add great extras like a 6 speaker sound system with sub-woofer so loud that when you play your latest shooter game, your neighbors ring the police thinking the sounds of gunshots coming from you house are real! In fact a workstation can be adapted into a full one stop office and multimedia center with a joint printer/fax/copier scanner, a digital camera, music player, DVD theater system, etc.
Another advantage of a tower over a laptop is the ease of upgrading. With a laptop the equipment is so tightly squeezed together that only an expert repairer dare enter the system and there certainly isn't room to add in more stuff. Whereas with a tower even most novices can learn how to plug a new graphics card, or replace a hard drive, increase the memory by inserting another card. Open most towers and you will see lots of space for all sorts of additional equipment Plenty of space to collect dust too, so don't forget to gently vacuum and clean it now and again - circuit boards, chips, etc don't like dust.
I hope this article has helped you with your next computer purchase decision. Of course if your wallet is big enough you can buy both!
