Kate I cannot speak for Bob - but I would love to move to P&G except...

It does not have custom key definitions

It does not have the 'pro' PDF export options

It does not even have some simple but incredibly useful UI functions, such as select by holding down alt and dragging

Just three examples, I could go on.. but in short, it is a 'castrated' version of the real thing

now..... I can live without the latter of those three.. but custom key definitions and PDF/X output I need.... so it is not an option for me

EDIT - oh and it's not 64bit... and it does not do multithreading... they are important too; very; sorry.
