Another technology dilemma: tablet edition

About a year ago, I wrote about my difficulties in choosing a new cell phone. I ended up with the Android-powered Samsung Captivate, and with the possible exceptions of no physical keyboard and an excruciatingly long upgrade cycle to Froyo, I couldn't be happier with it.

Now I want to buy a tablet. The iPad 2 is the default choice. It has a commanding lead in the apps I care about (think online newspapers and magazines), a nice size and shape, superior battery life, and a price that's inexplicably better than similarly powered tablets.

So why not just buy one? First, rumors of a sharper-resolution model this summer makes me want to wait a few months -- the main appeal of a lightweight tablet for me is e-reading. At the same time, I want to see what Android alternatives might be available by then. One possibility is the Nook Color, which is supposed to be getting a big upgrade this month. While I don't know whether I can live with the measly 7-inch screen, the idea of a low-cost Android tablet appeals to me. I do think Android is going to dominate the mobile market in the long run, and dealing with just one interface would be easier. (I already find myself looking for Android buttons on my wife's iPad.)

I wish someone could refute the iPad 3 rumor and just let me buy something already.
