There is absolutely no doubt that the Samsung Galaxy S2 is the best phone on the planet right now. It really is as complete as you can expect from any phone currently. Sure, you could perhaps add a better camera to compete directly with the Nokia N8, and a notification LED is a something I always want in a phone. But in the grand scheme of things that is nitpicking, really.
The fact is that the Galaxy will still be one of the best phones in the market six months from now, if not the best. I would even argue that in a year from now it will still be a very competitive phone, hardware wise, and will be able to perfectly run anything you throw at it – the dual core processor and 1 GB of RAM will make sure of that.
But the important thing about the Galaxy, and what the other manufacturers should take note of, is that when you create a phone with the right hardware, when you don’t pull any stops, people will flock around that device. It will be talked about, it will get press, it will get attention regardless of the platform it is running on (whoever said that it is all about the software?); so the next time you manufacturers want to create the new iPhone killer, have a look at the Galaxy S2 and let it inspire your hardware decisions.
