That's the sad part. Most people don't even know that Apple and iStore are not the same thing. My Macbook Air SSD experience was a perfect example of how Core charges triple the price of what Apple charges.
However, people will still buy from Core since we don't really have too many other options for buying Apple products in SA.
Wait, you're complaining that it doesn't include reachability? The link you gave literally describes Reachability as something that lets you use the phone with one hand - ergo Apple introduced it for larger phones. Why on earth would you need it with the diminutive SE.
Also, if you're unhappy a company doesn't point out specs that aren't the best in a marketing/press event, but is perfectly upfront about them on the specs page on their website, you must be unhappy a lot.
I think the phone has been ridiculously over-priced by Core, and if Apple could have their own presence here and sort it out that would be great, I would consider the phone then, so no I am not anti-Apple, but I am not a fanboy either, I currently have a Sony, I just think your post screams of wanting to nitpick.
