Some questions about Ipad Mini

1)

I'm reading your wonderful review on Ipad Mini but I don't understand this part:

" But how does it look? Well for starters, it's a really good looking display in general terms. Apple is using the same treatment here as it does on the iPhone 5 and iPad, and it makes for a crystal-clear screen that seems to hover just a tiny bit beneath glass. Colors are vibrant and blacks are deep, and games, photos, and video look terrific. ".

What do you mean with "Apple is using the same treatment here as it does on the iPhone 5 and iPad, and it makes for a crystal-clear screen that seems to hover just a tiny bit beneath glass"?

I'm afraid my english is not to good for undestanding that section.

2)

In the "Verge review" what means

"Those speeds are more a testament to the fact that Verizon's LTE network has slowed slightly thanks to the iPhone 5 than to the iPad's capabilities."?

In the part:

"Adding cellular connectivity to a small tablet feels like a no-brainer, moreso than it does on a full-size 10-inch tablet. You're much more likely to be toting it around with you in places without Wi-Fi coverage and it's a real boon to just have data simply available when you do. If you frequently tether, the iPad mini makes a lot of sense too. iOS 6 is simply rock-solid when tethering via USB and the iPad mini lasts forever as a Wi-Fi hotspot — though there are still some issues getting the initial connection going with iOS. "

I understand so:

"adding the lte to ipad mini is ok in the cases you are off wi-fi places and for che tethering utility that made this ipad mini in a very hot spot wi-fi. Is correct?

3)

Another section unclean for me:

"because the screen real estate is so much larger than an iPhone but icons are now roughly iPhone size, apps with lots of navigational elements can be a little less intuitive to navigate. Furthermore, the keyboard size feels altered — most notably in portrait — and the keys don't seem tall enough for my fingers. On the other hand, the mini makes landscape typing a lot easier"

Could you explain and synthetize the question and the problem the apps have on this display?

Thanks very well! (sorry for opening so many post!)
