CMS and ATLAS: original TDR versus what they are now April 26, 2006

I am meditating on the proceedings paper I need to write for a talk I gave in Corfu last September. It was titled "High Pt Physics from the Tevatron to the LHC", and it discussed the current Tevatron measurements which are most relevant to the first studies that CMS and ATLAS will be doing in a couple of years from now. Not only "what to measure now which we will not have a chance to later", but -more important- "what can we do now to help LHC reach higher in precision and discovery" (small x PDFs, for instance - high rapidity psi or Y->mu mu springing to mind).
I was thinking about the present status of the CMS and ATLAS detectors, and as far as CMS is concerned, I think the original design was quite a bit less "multipurpose" than it is now. I mean, we now have a pure silicon tracker, when originally it was mostly MSGC. And we now are building a EM calorimeter which is better than what was proposed at T=0. And the very same name, allusive of compactness and accent to muons from H decay, betrayed a less marked concern on the versatility of the device, when a name was given.
Anyone out there who wishes to comment on the ATLAS original design versus present construction blueprints ? I do not know the story of ATLAS very well… Maybe you can help me pointing me at any documentation ?

I am testing a new webcam these days…
Just for fun, I tried to record myself while I play a tough part of the third movement of Beethoven's "Appassionata" on the piano. The recording is not of very good quality, and I make several mistakes - oh well, did not have the time to try it on and on until I got it played decently.
If you want to have a look, and to see just how much I suck, it is in

Be careful though, it is a 26Mb file…

I realized today I have not posted a picture of Filippo or Ilaria here for a while…
While I know why I did not - the number of pedophilists surfing the web is a warning to anybody - I think one picture is not going to matter much in this mare magnum…
So, I picked up a picture I like. I took it last summer at the Rifugio Berti, close to Mount Popera:
