Most laptops that are bought at ultra-low prices turn out to be machines that are in dire need of major upgrades, before they can be optimally used (or resold). There are many of us who find this to be unfair: because when we venture out shopping for the cheap laptops, we expect to get machines we can immediately put to use (or immediately put up for resale).
Now in order to understand why most cheap laptops turn out to be machines in need of urgent (and major) upgrades, you have to take cognizance of the reasons as to why they are sold so cheaply, in the first place. That is where it turns that, in most cases, it is due to certain deficiencies noted in them that the laptops are sold cheaply. So the vendors of the cheap laptops don’t (typically)sell them cheaply because of their ‘charitable natures’ of because they don’t like money. Rather, the machines are usually sold cheaply because that is the only anyone could buy them, given their deficiencies.
More often than not, however, the deficiencies in the cheap laptops turn out to be issues that can be amended for, through the upgrades we are talking about; hence the reason as to why most cheap laptops require such upgrades.
