I feel like you're arguing disingenuously. You certainly don't believe this yourself. You haven't given up your videogame consoles to play games exclusively on the iPad. You haven't given up your computers and laptop to compute exclusively on the iPad. You haven't given up your home theater gear to watch content exclusively on the iPad.There's not been a single website I have had to deal with ever that has issues with safari. I would be interested in seeing an exhaustive list.
As always, a lot of those can'ts are "I don't wannas". Maybe the interactions don't feel natural to you, but they exist and work well if you learn to work -with- them and actually embrace things like the magic keyboard.
Because like us you know that the iPad is not categorically an adequate replacement.
