iPad is much more niche compared to iPhone. Not everyone wants/needs a consumer device to lounge around with for the price point. Everyone wants a phone. And to people like me, the iPad keyboard is simply unusable in landscape mode. Has this changed? No idea why they insist(ed) on stretching the keyboard across the entire screen instead of leaving half of the keyboard accessible to either side with thumbs. Even if the keyboard has been updated, the larger form factors are just too large and clunky for 2-handed use.
