PDF is phenomenally useful, and phenomenally irritating when you need to do more than read it. I wasn't at all surprised when Adobe told me they had user research saying people spent more time looking for features than using them in Acrobat 9; I either have to leave the Tyepwriter toolbar for filling in forms that aren't coded as real forms (so, every PDF I have to fill in) up on screen all the time, or I hide it to get more space to see the document I'm filling in and then spend ages trying to remember what the Typewriter is called and where it's hidden. I spend hours every month making and reviewing comments on large PDFs for IT Expert, wondering why my cursor sometimes is allowed to insert text and sometimes isn't. To be fair, any tool that's powerful is going to be complex. Let's say it's just not a fluid, intuitive experience - and I'm looking forward to Acrobat X next month.
The beta was announced this week: here's what I thought of it. Acrobat X: a first look Adobe's Acrobat X offers a cleaner interface and a welcome selection of feature improvements, some of them long overdue
