I am amazed by the power of my Galaxy S3.
It is as flexible as a PC Windows computer, you just drag and drop files to its directory, and run the appropriate apps to use it, music, movies, all work great. It is a perfect complement to my Windows 7 computer. In a Iphone, all transfer must be done using Itunes, and it is very limited and frustrating-
One of the best uses I can do is using this phone to download movies, music, and youtube videos, then when I am back home, transfer the files back to my Windows PC using simple drag and drop with windows explorer. Amazing! You cannot do it with Iphone, no way! You have no limitations using Galaxy 3.
Android is based on Linux, and Linus is based on Unix, its power is astounding and amazing in the Galaxy S3. I tried and ran the old DOS Foxplus and Microsoft Foxpro database program in it, using a DOS emulator, and they ran perfectly, no problems! Better if you download a transparent keyboard in the play store. Amazing!
Sometimes I wonder why Microsoft does not allow us to run in fullscreen our DOS programs in Windows 7 and 8 like the Samsung Galaxy does. In this way, the universe of programs you can run increase dramatically. You can have both worlds, Unix( Anroid) and Microsoft DOS.
Almost all the apps in the Play store are free, you can download the ones to suit your need. The selection of apps are comparable to IPhone IOS appstore. However, there are fewer games for the kids. But for adults, there are more, because adult apps are allowed. I spent more than a $1000 for apps for my IOS devices, and $0 for my Galaxy S3. There are many outstanding apps, including an amazing app for downloading Youtube videos at a speed faster than downloading a mp3 in a desktop PC, incredible!
There are more beautiful apps for music and streaming using the Galaxy S3 than Iphone, because they are allowed and legal, and not allowed in the Itunes environment.
Apple also made money from you by storage upgrade. In S3, upgrade using a 32 g. SDcard is just about 20-30 dollar, you have to pay more than $200 for a 64 g. Iphone.
The processing speed of the CPU is faster than Iphone 4S, my Flipboard program run faster in S3. Most apps from the same vendors run better in Galaxy S3 than Iphone 4S, noticeably movie and music live streaming apps. I used this phone in America to streaming live tv program from China and Hong Kong, watch live soccer games from Spain and Europe, and streaming and downloading musics from other countries. Downloading a song of 4 mega is less than 10 seconds, faster than a desktop computer.
However, I am a computer/math professional. From my point of view, Iphone is better for the majority of people for its easier user interface, Iphone just plug and play, need to learn nothing, Apple has done it fantastically to the mass with almost zero learning curve. Galaxy S3 is better for the professional who knows and understands computers and programming to exploit its resources. I spent some times exploring and learning my S3 interface and capabilities, at the beginning I was confused and lost!
