Wow! I was very surprised by the big number of feedback I got when asking tips for my new MacBook! I'd like to say you a big THANK YOU! You are great. I already installed iStat Pro. I liked it very much. I also installed Adium, NoeOffice, Transmission, Songbird and I'm still downloading and installing other suggestions. One drawback I saw was that after installing some applications, my solid rock brand new MacBook started to hang when shutting down! :O I uninstalled iStat Pro as I think it is the only low level thing which could give me this type of problem. Until now, I already shut down my laptop two times and the problem seems to be solved. I installed the 4.6 version on my OSX 10.5.3. I will try another version or a previous one later. I don't now but I didn't like the SongBird. I don't know why yet. I liked very much the Rhythmbox and I'm sad I can't get it on my Mac :(. For while I think I will keep using iTunes. But I'd rather use some other open...
