AndroidS3
Seriously! Ofcourse there are going to be alot of smartphones with much better specs then the s3 a year from now. As someone said, its natural technology advance - and quite fast I might add.
But do not despair - your (and mine aswell) s3 will probably play the majority of all games in a year anyway. You see, there is another aspect to it, and this is a aspect that we should not forget when comparing specs with other phones (its easy to focus so much on specs that we become blind for other aspects), namely the fact that the Samsun Galaxy s III is very, vey popular. There have been ALOT of s3's sold out there. This means that most developers probably gonna make games compatible with the s3 for quite a while, even if there are some hardcore Androids with hardcore specs out there then, because it would be stupid to neglect such a big part of the smartphone market that the s3 holds.
Ofcours the s3 is going to be 'old trash' one day (even though I find it hard to think of it as trash; but relatively speaking), but I personally believe that its gonna last (and be good) for some time!
You must be a very insecure person if you are starting to worry about your new high end phone growing old almost the same sec you bought it. If we would think that way all the time, well, then we would have to live in fear 24/7, becase there will ALWAYS come something that is better, no matter how new and technically advanced something is when its released...
So, calm down! Your s3 will be fine for quite a while, because there are so many ppl that have it so its good for business to make games, apps etc. compatible with it. And don't forget: It IS a very, very good phone
Relax in that thought, my friend
