Let me say this up front – I do not own an iPad and have only played with one for an hour or so. So my opinions are based upon the minimal interaction and the feedback from folks I respect. One of those folks is Fred Wilson – A VC on the east coast.
His most recent comments reinforce my opinion that the iPad is best suited for content consumption. You can create on the iPad – but I don’t think it is meant for the heavy lifting. Writing a quick email is one thing – creating anything beyond a simple Pages/Numbers/Keynote document is something else.
I feel the iPad is an additional device to meet your technology needs – not a replacement device.
