What are your thoughts
Pretty broad topic, that.
If you are looking for justification in staying with the older version, I have no problem with that. I only upgrade every other version. One reason is that newer versions sometimes bog down on older computers, and I am not willing to buy a new computer every 18 months.
Just follow the upgrade announcements closely to ensure that you will not get stuck with no upgrade path. At one time you could always upgrade from any version. Now it is only possible from the last three versions, and I could see that going to the last two versions in the next release (since the financial results of the last version release were less than Adobe had hoped for).
