I can sort of understand his worry about Blender though…
…me? I love Blender so much that I’m a well known Blender “kook” in Denmark by
now, so I can sort of appreciate the worry.
So how do I feel?
First, let me explain why I feel like I will tell you I feel (got that? 
) Read on:
Lets rewind a bit, and take a look at where Blender started out.
It was a small - for internal use - modeling & editing & game-developing suite
that was relatively primitive in comparison to the big well known packages out
there, at the time!
When it was released (freed) to the public as GPL, then the developers came
rushing in to become a part of this “at the time” very bright piece of software
because it had a lot of potential, and developing something like this from
scratch would be much harder than working on what was already created.
With all these “then new” developers rushing in and contributing like
there where no tomorrow - Blender became HUGE. So huge in fact that
you could do entire productions with it - in a professional quality, and many
got their jobs in the industry with Blender (I am one of those).
Blenders success isn’t based on the fact that it’s free - it’s based on the
community contributions - and the many dev-geniuses that use Blender
as their personal “testing & proving grounds” for new innovative ideas, programming
skills and other reasons I’m sure they know better than me.
Blender 2.49:
Blender 2.49 has come a long way, it is an eclectic collection of developers
efforts, we have numerous features that are considered separate plug-ins
in other, bigger, commercial packages. All these features have their
ups and downs, some are better than their commercial counterparts
and some are inferior. This is what you get, take it or leave it - or develop it
if you think you can make it better, this is largely how it works.
Blender had an Achilles heel though, and that was considered both it’s force
and a problem. Personally I experienced that I could model twice as fast
as in 3dstudio max in Blender with that - more efficient interface, but many
beginners or people coming from other packages - had a really hard learning
curve - mastering Blender, this has been a much heated & debated discussion
over the many years, but as the features grew - there was no doubt, something
was needed to be done, otherwise - the features just won’t fit.
Blender 2.50
Blender 2.50 isn’t just about the interface, it was MEANT to be the big
interface change, but it became a huge daunting re-write, and new features
chugged along with the now maturing developers, this of course - creates
some major issues since Blender isn’t just developed in-house, but across
the borders - and when you’re making THIS much change to a now pretty
big piece of software, working together and controlling all the code, synchronizing
it all into a perfectly tuned piece of production software, is such a daunting
task - that I can only IMAGINE the organizational power behind this to be
an equally daunting task. Kudos to all of them for doing it, and following trough.
And thats why:
I’m a bit worried about it too. This is the BIGGEST Blender project so far, you
can imagine how hard it must be on a developer and the team working on the
same thing for so long, and so many changes that literally affect the ENTIRE CODE,
and with new things being incorporated at the same time when the backbone
also “morphs” with the changes taking place every day - then you come to
realize - THIS WILL TAKE SOME TIME!
I’m in no way expecting a complete 2.50 in a couple of months, that would be
asking WAY too much, I’m seriously IMPRESSED how FAR and how WELL
the developers work together, and how FAR they’ve taken Blenders usability.
That brings me at rest, because - seriously - they’ve come this far, and believe me,
this will only be the beginning of a better piece of 3D software the world have seen.
I’m using the “SVN” dev. version all the time, and find it really HARD to go back
and use the old 2.49. So personally I can pretty much guarantee you all out
there that you’re in for the nicest Blender by far!
- It’s getting very intuitive (yes, even more than before)
- It’s workflow is actually improved by all the real-time features, you can
now for example…adjust procedureal-textures & colors in real time while
sliding the values, before…you had to “stop-and-check” if you had the right
results, no more…everything is REALTIME.
- The new realtime environment affects absolutely every aspect of Blender,
and I guarantee you that you will love that, and you can combine more modifiers
in far more creative ways than before - and STILL experiment realtime, some of them
of course…will demand a modern computer, but hey - Blenders development shall
not be hindered by “slow computers”. After all - it’s free, so now you can afford to
spend all your money on the actual equipment 
Your worry about the colors & theme are easily laid to rest with the fact
that Blender will be completely theme-able, meaning that you’ll literally be able
to customize every aspect of Blender in time. Everyone can submit their own
idea of the “Perfect Blender Setup”, so you’ll have more fun than ever.
That was a long read - sorry about that - but that question deserved some attention imho.
