Regarding MBP versus MBA, one of my graduate students just got a new MBA and
her machine is much faster than my MBP 2.8 GHz Intel Core 2 Duo with 4 GB RAM.
Both machines are running Lion.
The new MBA is hot, only disadvantage you can't lock it down, there's no option
for it.

Dear Colleagues,
Lion is an reality all developers have to live with. While I
agree that it would be a bad idea to update one's primary
development environment to Lion, it does seem a good idea to have
at least one system with sufficient memory, disk and good enough
graphics and the new UI (user interface) to be able to wring out
problems, especially on the UI side.
So the question is: Is a new MacBook Pro or new MacBook Air
sufficient for such testing, or is something heftier with a
studio display necessary?
Regards,
Herbert

Hi
My two ha'porth.
If you are thinking of upgrading your sole Mac software
development box to Lion I'd say don't do it unless you like a lot
of pain. Anything built on Snow Leopard should run okay on Lion (my
Tiger builds seem okay on 10.4, 10.5, 10.6...), so unless you really
have an over-riding need to move to 10.7, I'd hang fire.
If you're only running applications and not developing, you can
always shout at the developers if things go wrong.
My plan is to install Lion on a spare bootable disk and see what
happens - if all else fails, at least I can ignore the upgrade until
Apple release 10.7.1, 10.7.2, etc and fix most of their screw-ups.

Hi,
Overall, the transition from 10.6 is seemingless, crystallographically-wise.
Of course you need to have the new XCode 4.1 installed, and you
should also download new, 10.7-dedicated 64bits gcc/gfortran/g77
bundles from http://hpc.sourceforge.net/
And then, CNS, Phenix, CCP4, etc... will just run perfect.
I had to reinstall Coot -- but that's minor.
(Mac)Pymol also works fine, yet (for some reason) uses a lot of
resources even when idle.
As per the Upsalla Soft. Factory programs, you'll have to recompile
then using the above mentioned bundles, or get already compiled
binaries from Mark Harris.
You'll also need to recompile Gromacs (and fftw3) if you're using
it -- but it then works great.
I agree with W. Scott on the fact that the new OS is really greedy
in terms of resources.
I surely wont upgrade my other, older mac computers that run just
fine on 10.6.
But if you have a new Mac, Lion is is really neat.

Hi Phil:
I've found few, if any advantages. I fear for the future.
I've had problems getting coot to run stereo due to the X11
implementation in 10.7. Apart from that, no major problems with
crystallographic software.
Lion greedily uses memory, and any computer I have with less than
4 gig of memory has become extremely sluggish as a consequence of
the upgrade. Ideally, you need 8 gig.
Even with that, on my 2010 mini that I use for music playback, I
regressed to 10.6.8, because of the audio interface. (It seems
less robust, more prone to dropouts and now lacks integer mode
output).
Sara has been screaming at me for the last two weeks (nothing us
usual in of itself) because Apple decided to get rid of Save As.
Xcode and the compiler set is free again on 10.7.
I've put some suggestions here for how to get rid of the most
annoying new features:

All the best,

Is there any opinion or experience about whether Lion is ready
for crystallographic use? Should I upgrade?
