Having never used a galaxy I looked up the hardware specs. The G2 was on par with the iphone 5..
I have no idea about G2 aps or the mp3 player, must be a downside some where, or ipod users would be migrating to G2 over ipod 5.
You have to be very careful when comparing specs across platforms. Except for some specs, such as dimensions and storage capacity, most specs cannot be compared. For example, the android device may have more RAM, but what good is it, when the iOS device is
faster with less RAM, because the software is more optimized and uses RAM more efficiently. So the android with MORE RAM is slower than the iOS with LESS RAM... and what do you care about: a number, or how fast your device is? Same for chip speed, graphics and so on.
Bottom line: you can't just compare numbers and draw conclusions. You need tests - and real life tests are better than some synthetic tests that don't describe real world use.
Ultimately, it's not even about the specs. It's about user satisfaction with the WHOLE package. How is it to use a given device vs another one? Maybe one is a bit faster, but tends to crash a lot - so what good is "faster" here? Maybe one is a lot easier to use, so you are only tapping two times to accomplish something, whereas another device is "faster", but it takes SIX taps to accomplish the same thing - all that speed is wasted when it takes the user longer to get to the point of completing the task or operation.
FWIW, Apple's focus is user experience. Which is why they put a lot of emphasis on real-life usefulness and ease, and not on specs. Most companies cannot match this, even if they can be ahead on hardware "specs". I've handled some Samsung products that were amazing hardware specs, but the software sucked badly, and in the end, I preferred the "lesser" hardware that had MUCH better software.
It's about the whole experience. Comparing numbers is just not going to tell you much of anything.
Grab both products and compare in your own hands for your own uses and your own priorities and your own taste. That's the only way to really make a fair comparison for yourself. And you may reach a different conclusion from your friend who has different needs, and that's OK too. Choices are good!
