I was really looking forward to Publisher as a future proof replacement auf Page Plus X9 and was very excited when the first beta came out.
Unfortunately I have to conclude for myself, that Publisher makes creating my documents much more complicated than Page Plus, which is why I won't jump on the train - at least for now.
But let me explain why...
Page Plus has been my DTP software in the past few years whenever I needed to layout photobooks, which also contained text. So my publications are very image centric.
I love Page Plus, because I can preload all my images into the Source File Pane where they are always at my hand, whenever I want to insert one into the publication or whenever I want to exchange an exitisting picture. Also I can always see which images I already used and which ones are still available. It behaves a bit like photobook-software provided by Photobook-Companies in regard to image handling, but it also provides all advantages of a fully featured DTP-Solution.
Unfortunately Publisher is no way near that for my purposes. The fact that I cannot place Images in a workspace without placing them immediatly into the document simply is not very comfortable. Also exchanging photos is not as intuitive. At last I can never see which images I already used, which is kind of bad if your looking at publications with 100-200 pages full of images.
So for now I will (have to) stick with Page Plus, but I hope Publisher will become a full replacement in the future.
