Or its not that much different. . I want to buy a tablet, and the choice lies between these two similar tablets. . They both have almost same specification, the only difference is the first one have screen with ips technology but not sim card slot, although the other is the opposite, it have a sim card slot but without ips techonlogy. . Thanks for the answer. Basically… Although I'm talking about computer monitors, the same should apply for tablets. My previous monitor was a standard 21" LCD/led-backlight one with a resolution of 1440 x 900. My current one is an 27" IPS panel with a resolution of 2560 x 1440. The most obvious difference (besides screen size ) was the viewing angle of the IPS panel. The viewing angle compared to my previous monitor is remarkably different allowing me to view my IPS monitor practically sideways compared to my old one. Another difference I realized was it had more "vibrant" colors and it displayed the colors much more clearer, if that makes sense. The only downside about the IPS panels is they usually have a slower response time. But this shouldn't be noticeable at all compared to the other one, as I've yet to see a difference in response time compared to my other monitor and this is coming from an avid gamer who plays a lot of fast paced games. Pros – Much wider viewing angle (should make it easier on the neck), more vibrant colors Cons – A slower response time, but should not be noticeable.
