Assuming this is a serious post and you are not someone MS is paying to promote their products. I can think of a few issues here:
1) Tablets are not the best devices for office productivity. If you want to get a lot of writing done, a laptop is far better.
2) The surface is unlikely to be very useable on the plane, on your lap as the keyboard is too flexible. Typing for long periods of time on a touch screen is not fun.
This is the problem with the surface, pretty much it's only advantage over the iPad is that it has Office. But Office on a tablet is not the best way to get work done, a ultra book is a much better option. Now there are some tasks that can be performed better or just as good on a tablet, but then they will be better on the iPad because of the greater number of quality apps.
Wrong. Wrong. Wrong.
1) Tablets WEREN'T the best devices for productivity until the Surface came along. I CAN get a lot of writing done, finally, with a tablet thanks to the razor thin keyboard cover with backlighting on the Surface and a built-in stand.
2) The Surface isn't usable on a plane? Have you EVER flown anywhere and done work? You realize there's something called a dinner tray that everyone rests their laptop on to do work? Most people don't put the device on their lap. Please...
So no, the Surface's only advantage over the iPad is not just that it comes with Office, but that it has two main things that totally separate it:
1) Built-in retractable stand.
2) Razor thin backlit keyboard cover
You see all those third party keyboard covers and stands for the iPad in Apple Stores and other stores? You see how much the market is peppered with these two accessories? Yes, you do see it. And that's because people want this functionality and have to deal with crappy third party garbage to glue onto a device that was never meant for that functionality in the first place.
Look, I'm an Apple guy but I'm not a fanboy. My hat's off to Microsoft for nailing the productivity part of a tablet. The Surface is flawed in other ways like the iPad is flawed for productivity, it's not perfect. But once you use a tablet with a retractable stand built in and a keyboard cover that's razor thin, you literally have 0 third party accessories and total productivity.
I'm upset because I like Apple and the iPad. There were some articles that came out about smart keyboard cover patents etc. before the event. But nothing. Same old slippery, overly simplistic tablet. I want Apple to make this thing productive.
