Mouse support would turn the iPad and the Smart Keyboard combo into a true competitor to the laptop, as well as position it as a direct competitor to devices such as Microsoft’s Surface Pro… More at ZDNet.
No it wouldn’t.
Mouse support would make a big different, but to presume that this change alone would build a laptop competitor is pure folly.
The list is long to make the iPad replace a laptop and it reaches the point very quickly that you may as well buy a laptop anyway.
Full multi-tasking OS, multiple users, really good keyboard, tons of power and on and on and on.
The iPad is not a laptop and it never will be.
