The high resolution screen is just a gimmick - there's no real reason to produce a screen resolution higher than 1920xZZZZ (top suit screen size ration).
There is no content available for that high resolution, and the tablets screen size and interface really aren't useful for work.
30" computer screen resolutions are typically 2560x1600 (16:10) /2560x1440 (1440p /16:9) or 2560x1920 (4:3), but while the 2048x1536 resolution is available for the "new ipad", there's a well argued case that practically no-one will ever be able to determine the difference over 1080p regardless.
The vast majority of people can't tell the difference between a 720p and 1080p TV on anything smaller than a 40" at a few feet.
Those large 80"-120" advertising TV walls (using actual TV's, not those crappy sports TV's with chunky LEDs) are all driven at 1080p ... and until you're up close and personal, no-one could tell.
It's nice that the resolution has increased, to match my 2 year old Galaxy Tab 7", but the resolution is overkill and the content will look worse because playing readily available (1080p) video's will result in interpolated pixels, which is inferior to a native (matching) resolution.
