She spent the entire article talking about how these apps could easily replace the laptop programs, even saying her husband wished his company made the switch because it was better for business, and then at the end says she doesn't think it will replace a laptop, lol
She missed a few important facts though that would probably change her opinion.
1: That MS Office that she was so fond of is coming to Android and iPhone/iPad. The rumored launch date for the Android version is in March. You will then be able to use it on any phone/tablet. If her only beef with it was the tablet it happened to be installed on (was too big), then this point will be soon be moot.
2: The Microsoft Surface tablet that will be launching soon has a keyboard built into the case. Similar cases are available for every other tablet out there. She also mentioned that you can get a wireless keyboard if you want. If her only concern for tablets in general is typing works different than on a laptop, this is already a non issue.
3: These apps are still relatively new and have already improved a lot over time. They will continue to get better. Even though her husband, a business user, said it's already good enough and he hopes his company makes the switch, you can absolutely expect these apps to get a lot better in the coming months.
4: Some tablets will be running the same Windows 8, with the same MS Office, as a desktop computer. There will literally be no difference. And they will come in all shapes and sizes. They won't all be as big and clunky as the one she tried. Her only concern with that tablet was she thought it was too big, and that point is moot.
5: The old man that said the screen was too small on his phone could have either got a phone with a bigger screen, connected his phone to his tv or a monitor, or tried a tablet. Just because he thought the screen was too small on that particular phone doesn't mean the laptop is the only alternative.
