Most laptop buyers are specifically concerned about the budget. It is obviously a wise move to check for the most reasonable deal out of the available options; however, choosing the cheapest laptop will certainly provide fewer features and low-quality assurance.
For instance, if you have to choose between dual-core and quad-core, the dual-core system will clearly be cheaper than the quad-core one. So, if you opt for a dual-core processor to save a bit, you will certainly miss out specific performance power when compared with a quad-core system. Furthermore, you might experience cluttered performance as the system on your laptop will be unable to handle many applications at once.
So instead of focusing on the lowest price, you should first decide the purpose of buying a laptop for yourself. Make a list of features which are a must for your laptop, then cross-check it with the available options.
