Sad to see that a lot of people are not getting it. The iPad is a revolutionary device -- it is the manifestation of transit, the transit from the classical desktop paradigm over to the new wave of ubiquitous computing.
Applications like iWork for the iPad and the OmniGroup products are going to make a substantial difference. Software developers will now stop with overloading their apps with features (of which the typical user rarely uses more than 20%), but concentrate on streamlining the human computer interaction instead -- hence improving productivity and... fun with computers!
We -- the LaTe App-Developers -- are embracing change and will create software for the iPad. Exciting times to live in!
Update: Matt Gemmel got it, see his blog post with great insight into the relevance of the iPad.
Update II: Joe Hewitt as well, see his blog post.
