About that moving from enthusiastic start to boredom and lack of support...
From my point of view - take navicore for example... as I've seen the demo I'm not going to pay for it... it's simply not enough for me to be worth payin g for but - there's no update.
On the other side look at PC scene... did NERO came to the point of being "all included" suite because of user needs? I don't think so. They gained from their product and had to do something not to loose money. BUT - hey ... the first nero wouldn't be so popular if it was simply broken. And that's the way I see many (in general) OSS applications. The first release is far from being useful and - when it's "one man show" - the story ends.
Some say "do it yourself or find someone who will"... wake up - it's been long ago when users were all programmers.
I simply can't fix it and I don't know anybody who could do it for me (please John do it - a great number of people will PROBABLY be thankful). It's simply not that easy.
As some justification - try to convince Adobe to release PS for linux just because You want to use it on this OS.
