At the 2014 Consumer Electronics Show, Samsung (NASDAQOTH:SSNLF) unveiled a pair of enormous tablets. The TabPro and NotePro both feature 12.2-inch displays and are geared toward productivity. Samsung even went as far as to create a brand-new tablet-optimized interface called Magazine UX, a departure from its regular TouchWiz interface for Android. The new interface further de-emphasizes Google's presence on the device as well. Introducing a new core interface is always a risky proposition. Possible leaked pricing data also suggests that these new large tablets will be rather expensive.

AppleĀ (NASDAQ:AAPL) has been rumored to be testing a similarly large 12.9-inch tablet that's being referred to as the iPad Pro. Samsung's new tablets call into question the viability of such large form factors altogether. However, Apple does have some advantages in build quality and is known for making its devices the thinnest and lightest available. If Apple indeed goes for a 12.9-inch display, it might be going too far.

In this segment of Tech Teardown, Erin Kennedy discusses the prospects of an iPad Pro with Evan Niu, CFA, our tech and telecom bureau chief.
