I have had my Apple TV for a couple of months and love it!
I would recommend getting the 160GB hard drive version that is being phased out. This older version is also capable of streaming, and when I first synced the Apple TV I was initially disappointed with the sound -- it did not sound quite as good as my CD player going to my DAC. However, I realized that what I initially heard was streaming (that is, I began listening before the songs were synced to the Apple TV harddrive). After the songs were synced on the Apple TV hard drive, it sounds every bit as good (and possibily better) as my CD player going to my DAC.
