neutral on usability - There'son;y on or two applications that I prefer for userbility/functionality over newr ones i.e DW CS5.5 over DW CS6 - Use both PSD CS5.1 and CS6
As for usability, I can't think of the technical term for it, but the way the GUI is designed. ie how long it takes one to move from a to b and how many actions are required to reach something without addition 3rd party software's. Don't get me wrong they are far more usable and easier to use than their competitors but they are slowly slipping away from that.
The new Mac Pro's should be out soon
I'm not referring to hardware but the software. Take for example Final cut pro being made redundant and the introduction of Final cut pro X which is more like a glorified IMovie than a pro video editing software. Many people are turning back to Avid for this reason. This also ties in with them closing things off like the User Library which is now a hidden. I prefer to clean things out like preferences and remains of old installs manually rather than use a 3rd party software. How long before they hide thing like the system library's or worse lock us out totally. Even little things like not being able to access the etc/host file via terminal anymore. If I want to access that I now have to show hidden files and go in and open in TextEdit manually to configure. It's all now becoming more of a hack/work arounds.
Adobe have begun dipping their toes in water with an online web dev program
I've not heard of that but that is scary and tells me it's starting to happen. How long before Adobe go down the route of Final cut pro or even worse abandon it for more online services.
In response to some of Virts comments
No, but maybe actually make the updates more... Update-like

Make it so it can actually be deserving of the price it costs
The problem I have here is that they as well as other companies release softwares too early when they should be still in the Beta stage as they are usually buggy. They rely too much on the end user to report bugs and work out workarounds and third party companies or open source to improve things and then they release these things in a later version. They should put us all on a wage or give the software out for nothing

It's all greed and rush rush rush to get something out before their competitors. I don't like the way the whole computer industry eventually forces one to splash out their hard earned cash and update. Take Flash for example, If I had not managed to use a hack on my old perfectly good G5, I would have been forced to update to an Intel machine and the G5 would end up on a beach abroad or on a landfill. These companies are so environment friendly

This is because they stop supporting older versions and bad web designers (especially the big sites, social networking etc) don't cater for those on older systems and software. A lot of them don't degrade gracefully and ignore accessibility issues. It's as if all the companies are in cahoots with each other and just getting us to spend our money on them and upgrade.
makes me feel young again
Now that''s funny PMSL
