Google Desktop 2 and Talk

I have just installed Google Desktop 2 on my office workstation and hope to install it on my home machine later in the evening.
After installation, it is indexing the files. The 'sidebar' feature seems quite good, but Weather and Share Market info is meant only for those in US :( A big disappointment for us non-US people.
What u say of it? Any reviews?

Also, I plan to install Talk on my home machine. How it it. Has anybody used it so far? Any reviews?
