I'm sure I'm alone but I don't see Quark 7 and Indesign as direct competitors in the form of features or target market only in the sense they are both generally speaking DTP tools. I didn't word that very well but will endeavour to explain.
As a creative tool I find Indesign to be superior especially if you are savvy with the Photoshop way of working. The integration with the other Adobe apps is welcome but as a stand alone tool I find it very appealing and have used it since version 1. I don't buy the argument that it is bloated from a performance perspective, although I did find CS1 a little duff, when you weigh in how powerful it is I find it's peformance good and have used it happily on a 1GHz Powerbook.
Quark is the ideal prepress/print tool, it is fast to use (for the most part but I don't find it intuitive at all) and easy on the eye. I first used it at version 4 and in my mind it just hasn't evolved as it shold have since. Quoting 60% market share is one thing but I highly doubt the vast majority are using the latest version so the actual number of updates and market share would be reducing. I know a number of printers that actually bought up stock of Apple's OS9 compatible machines just to extend the use of 4.1 (still the best version IMHO). Most of Quarks power features are behind the scenes or for output it simply isn't a designers tool for the most part. Adobe has done well to make the impact they have with ID, the ability to bundle with other apps is a huge advantage as is making the undoubted king of image manipulation software for professional use.
The Quark mindset dates back to the dawn of DTP and hasn't really changed, I like version 7 but it isn't revolutionary it can't afford to be. Quark are not in a position to out Adobe Adobe.
From an education level Quark is still taught actvely (although not indepth) in the UK which is very important as this is where new talent is bloodied. As long as this is the case Quark will always have a place as it won't just be its stalwart users in its camp. Quark must realise though that the majority of students who get to use ID do favour it for its features and Photoshop like layout. If your a life long Quark user it is indeed intuitive if your not then it can be a real pain in the ass.
Quark has loyal users and rightly so but this is maybe born out of the fact they invested heavily in it prior to ID and not a reflection on its development progress. Framemaker is Adobe's real competitor to Quark if only they marketed it better. I think it would have Quark beat hands down as it doesn't try to be the all tools to all men that ID does.
As Blue Velvet said young designers favour ID. Quark in many ways is old school thinking and marketing (price is a huge issue) and it will take more than a logo change to swing that around.
On a completely separate issue Apple's education licensing does allow for upgrades through the use of retail upgrades. The license type however alters to reflect this. Can you not upgrade Adobe and Quark apps through the use of retail upgrade packs cheaper then buying all new education licenses? I've never had to do it so could be talking out my posterior but for individual users this is an option
