Sarah Perez’s OpEd on her experience with Microsoft Surface is anything but glowing:

It’s simply an awful tablet. If you remove the keyboard and try to use in portrait mode, the thing is too long and too narrow. It feels heavy because it’s too thick, despite being about on par with the iPad in weight. But if you attach the keyboard, you then have to be sitting at a desk or table where you can prop the thing up. It’s not a lap computer, which is nutty because tablet computers are for untethering you from a desk, and laptops have the word “lap” in them for a reason. Only Microsoft could come up with a way to make a tablet/laptop combo that forces you back to your desk no matter the configuration you select.
