Re: Excellent review; but "flaunting"?
There are Android phones available in a range of sizes, but most of the smaller (think 'iPhone' sized) models aren't as powerful as their 5" stable-mates. However, Sony make a 4.3" phone with the same quad-core (Snapdragon 800) chipset as this Samsung S5 (as well as the LG G2 and Nexus 5), waterproof and sporting a microSD card port. I'm not recommending it because I haven't used it, but on paper it ticks all the right boxes for some people.
I have used a couple of phones with the Snapdragon 800 chipset, and they are lovely and fast. The £300 Nexus 5 I recommended to my techno-curious old man, and the sheer fluidity of its UI has made it far easier for him to use it without getting frustrated. The one fly in the ointment is that Google have seen fit to make the KitKat phone dialler app 'smarter' than it needs to be, which can cause him confusion.
