I am an Apple guy, never owned and don't believe ever will own an Android. Yet I am afraid to say, Samsung is right. Apple fanboys made fun of the large Samsung screen, and Apple specifically said we create iPhones smaller so you can use them with one hand. Now they have changed their minds.
As far comparing yourself with others, Apple does it all the time. Each keynote they pull out numbers and brag about their market share and make fun of the Windows platform. They make fun of the defragmented market.
Making fun of competing products is lame, but when what you say is true it works.
The difference is that when Apple talks about numbers or gimicky features of competition, they typically are talking about Android phones/tablets in general, not specific brands.
I do not remember a time when Apple called out in a Keynote or any commercial any of Samsung specific devices saying that the GN2 or 3 or whatever, is too big, or the S-Pen is a gimick, etc... When they talk about fragmentation, they again, talk about all Android devices such as newer devices still bring produced with what, gingerbread or icecream sandwich versions of Android. We aren't talking about flagship devices which typically come with the most current version, we are talking about the low end phones that come with subpar hardware, 3 year old software and sold for free on a 2 year contract. The average person will see that as a deal since they can facebook, surf the internet and get email, text, and calls on a device that cost nothing up front for them. Your geeks are the ones that are going to want the newer flag ship devices with the newer software, highend specs, etc...
With the Mac vs PC ads from the 2000's, again, never calling out specifically Microsoft. Otherwise it would have been Mac vs MS. I still find those ads humorous though.
In their newer ads, Apple focuses on their device, it's capabilities, how it's built, how it can be used to bring people together or to share experiences, etc... I do not remember (doesn't mean there aren't any but I usually watch all of them) an ad that called Samsung, or any other Android company out specifically, to degrade their device or the users that own them.
This is coming from a guy that uses Windows 7 at work, Windows 8.1 on a 2 in 1 hybrid laptop, an iPad rMini, iP5 (soon to be iP6+), Apple TV3, and Mac Mini (late 2012). There are pros and cons to each of those, just like there are pros and cons of using android or not.
Mac OS: I like it. Not too bad, still getting use to it since I do not use it daily.
iPad: love it. Use it every day for email, iMessage, internet,video streams, etc... Love it for my wife who figures out a way to screw up whatever computer I give her (except the ipad). 2+ years with the same device for her and so far zero problems.
iPhone: love it. Again, every day I use it for the same as the iPad since it integrates so well with it. Use it daily during workouts with Runkeeper, Pandora, stock Music App, etc... Same statement about reliability for the iphone for my wife as the ipad above.
Windows 7 and 8.1: grew up using windows computers so I am the most familiar with it and comfortable but sometimes I absoluetly hate it since something will crash and it requires a reboot. Mostly standard so it is easy to find a program or device that will work on a windows computer versus say a Mac (still haven't dived into the Parrallels thing to run windows and Mac software on the same computer).
If you like android, stick with it. If not, switch.
