Working in the construction business, I would love to be able to have an entire set of construction drawings ('blueprints'.. though they're not really blue anymore) with me in my Pre for the various jobs I work on. Drawings for construction projects are commonly available in PDF format for bidding and other purposes and they are typically small enough that all the drawings for most small or medium sized projects could easily fit in the RAM in a Pre. The problem is that the Palm provided reader for PDF files wont allow users to zoom in far enough to see the details in these drawings. Sure, I could take pictures of an actual printed drawing and try to make that work but it wouldn't be practical for the larger commercial and industrial jobs I frequently work on with many mechanical and electrical drawings and details. Does anyone know of another viewer available for the Pre that has this functionality? Or, maybe this could be in a future update of the Palm provided PDF viewer.
