Jane over at Dear Author posted her first impressions of the iPad yesterday. Here's the intro:
I’m using the bluetooth keyboard to type this review out. I like the iPad a lot. I can foresee using this device everyday but it’s not the greatest ebook reader. I’m not certain if my frustration stems mostly from the software (the reading applications) or the hardware. I don’t think the iPad is a Kindle killer (or dedicated eink device) because I think the primary purpose of the iPad is not long form narrative reading.
I'm going to have to disagree with her somewhat. The iPad probably won't kill the Kindle, but then again, it was never going to. It weighs too much and it cost too much to be a threat to sub $300 ereaders. It's simply not in the same market.
But I do think that the iPad is a serious threat to the DX, Que, DR1000, and other large devices in that price and weight range. It is simply too good at what it does.
