I love the iPad. I really do. Getting a good iPad stand, however, can be a daunting proposition. There are a lot of varieties, things you can buy, things you can convert. It's pretty clear to me that for a lot of iPad use, a stand is mandatory.
I don't think the iPad is a one-hander. It gets heavy, and eventually I want to put it down. If I lay it flat, it's hard to type on, because the curved back (what were they thinking?) makes it wobble if you touch it. So here's a report on what I have found:the good, the bad, and the ugly.
First, a Seattle company called Padded Spaces sent me their product called Prop it Up. It's a bit large, and I think it might have been originally designed for laptops and netbooks. It is wide enough for a MacBook Pro.
You put your iPad on the plush, wedge shaped base, and you can adjust the angle from very low to about 80 degrees. The iPad stays in place, and I enjoyed using it. It is a bit large to be hauling around outside the house. The company makes a model that also functions as a case, so you pop the iPad inside for travel.
Of all the things I tried, this was the nicest iPad stand for around the house, but I felt like I should have one for several rooms, rather than move the thing around. I think if this product was made to fit the width of the iPad and generally reduced in all dimensions it would be a perfect solution. Prop it Up is US$39.95 or $49.95 with the integrated carrying case.
