Hmmm... I'll see about sending an email to IDM, but in my experience even though they do seem to find a way to respond in good ways to user feedback
insofar as the actual changes they make to the applications, the actual 'responses' to the emails are often... 'thanks, filed appropriately' in nature. And then without any other obvious feedback, you wind up finding out what you were asking about is buried somewhere in the next version. The info available about U3 specifically is really weak and lame... it's mostly just a bunch of BS marketing babble... and does a poor job of actually letting you know what it is and how it relates to you as an existing UE user.
The other products I use make it real simple... buy a license for the 'portable option' (which for me are around 10 - 20% of the overall costs of the app, depending on the app)... and you simply 'export' your regular desktop installation with it's settings and preferences to a u3p file. Same product... just an export option. This whole seemingly 'seperate product' nonsense and the associated cost just seems weird to me...
Anyhow, I wonder who even convinced them to
waste their time with U3... it's already being abandoned by the company that created it. It will still be 'around' for awhile I'm sure... but SanDisk is already partnering with M$ to create an MS sanctioned alternative that will have support inside Windows to seemingly be more 'secure', and SanDisk has stated they will 'work with software developers who worked to support U3 to help them transitioning to the new model.
This fact alone makes the whole notion of paying 50% of the cost of your existing UE product even more of a raw deal... I feel somewhat annoyed about it

. I've considered myself a loyal UE customer for quite some time now... not just years of 'if you do this I'll spend money' like some lamers. I've actually paid for three (MAYbe four?) versions now... but I'm looking at Notepad++ and other alternatives that I can run 'portably'... some of which are free right from the get-go.
And I'll tell you what, other editors can be just as good... in fact my main problem with switching is that I've been using UE for so long, I'm just USED to it. I don't begrudge IDM wanting to make money... but a whole other product for existing users to have to buy to run UE portable? Shame... and as close as up until just a month or so before the U3 release... emailing IDM about how they were actually going to deliver U3 after they announced it got a "we're not sure yet reply"... Lame.
Anyhow... paying 50% of the cost of UE for a separate product that runs on a portable platform that sucks and is soon to be killed off by the vendor that created it sure seems like a waste of money. When U3 goes bye-bye and we all rush to the store to buy cheap solid-state USB drives with amazing 100 GB capacities... what then? A $30 upgrade to a separate UE4 product...? grrr.
Unfortunately for ME as a UE customer... a change in my job recently made portable app functionality a NECESSITY rather than the 'nice to have' it would have been for me a year ago... And I'll tell you what... if I have to "learn" a whole nother application for use on portable USB, you can bet I'm going to switch on the desktop as well just so I don't have to switch my brain back and forth between application A and B modes.
If I sound 'angry'... it's more dissapointment than anger. I was stoked when I head about U3 capacbility because I thought it would just be an 'option' and that U3 would just be ONE way to run it portably... that was diss 1, followed by price (diss 2), and then SanDisk saying bon-voyage to U3 was just a twist of the knife. For my other apps, U3 is just 'one' the options... I would even rather have seen IDM go the route of the ProtableApps.com model than U3...
