Buying a mobile phone is a minefield of choices, from screen sizes, to operating systems, processor speeds and form factor. Adding to this is which network, minutes, text and data bundle to choose. This second step, after you compare mobile phones and finally decide upon a winner, is the one that can tie you into a contract for a lengthy period of time – currently as much as two years.
However, there is another way, namely buying a SIM free device – offering the freedom of a far shorter contract and leaving the choice of selecting network a separate issue. Either way, you end up paying for your mobile phone – the choice is whether you pay for it now, or pay for it later. If you pay for it later by opting for a contract, you could be using the same mobile phone for as long as two years, at the end of which it is dated and holds a low resale value – if any at all.
Think about that: 2 years.
In two years, we have seen mobile phones go from a single core 1GHz processor in the Samsung Galaxy S, to a dual-core 1.2GHz CPU in the Galaxy S II. And now, quad-core 1.4GHz processors are commonplace, as seen in the Galaxy S III.
Using that series of sequels for another example, we have gone from a 4-inch 800 x 480 screen to a high definition 4.8-inch 1,280 x 800 resolution display.
