How You Can Decide Which Laptop or Netbook Best Suits Your Needs?
Before purchasing a laptop careful consideration must be given to the specification rather than the cosmetic features and its presentation. Fairly often the acquisition of a laptop it is made as an impulse purchase and not found to be inadequate until it is used for some time. It's always most important to be sure that the notebook will perform perfectly in the course of the expected use that you'll be putting it to. There is nothing more annoying than a notebook that runs very slowly or constantly crashes and resets!
Different laptop usage scenarios shall be considered with the most to the least demanding.
Should you want to play the latest games and experience smooth clear vibrant graphics then you will want an incredibly high specification netbook. Most importantly, the graphics chip or graphics card should be very fast and contain lots of memory. Generally, graphics chips on laptops can't be upgraded so this needs to be considered when purchasing the notebook. Also you must try to permit for future requirements over several years assuming the laptop isn't to be replaced every year. Next consider RAM; without exception games will run smoother on laptops with large amounts of memory. RAM inside laptop can usually be upgraded as it usually becomes cheaper in the future. Processor speed can also be very important for efficient game playing, again the faster the CPU the better the game will perform. The processor can sometimes be upgraded in laptops. A fast large hard drive is essential for game playing as most games occupy a considerable space within the netbook, this can also usually be upgraded as required. A huge screen size, a full size keyboard, a blue ray DVD drive etc all add to the gaming experience but aren't usually of prime concern.
If you are going to be producing and manipulating video production files then a notebook with loads of RAM, a quick processor and two hard drives needs to be considered. RAM and fast CPU are necessary so video sequences can be manipulated quickly. An effective but not necessarily a high end graphics chip or graphics card will be required to ensure good rendering of modified images. Two hard drives are useful to ensure that the completed video production could be saved to the extra hard disk before burning with a DVD. The DVD drive should have a fast burn speed and ideally have blue ray capabilities.
If the main use for your netbook will probably be graphic design or photographic image manipulation then the processor chip, RAM and hard disk drive capacity needs to be considered. A quick CPU and great deal of RAM is critical in order that images an be modified and manipulated. Also a big hard drive is required as it is going to soon become full with large graphic images. Surprisingly, the graphics chip or lard is less significant than for game playing since the CPU manipulates and changes the image instead of the graphics GPU. A large screen size is probably desirable as the static images being manipulated will require careful viewing to make alterations.
If you are likely to use the notebook mainly for Internet and emails then any currently available laptop should perform perfectly.
If you're buying the notebook mainly for business use then almost any currently produced netbook is going to be OK, however, you could possibly find one that comes with a choice of business programs free at the time of purchase.
So provided the netbook just isn't primarily intended for game playing or graphic design or video applications then almost any currently produced netbook should be OK, however, it is sensible to consider future use and upgradability.
