As swell as that sounds, I've noticed many programs behaviour to not quite work as it would a ZIP, RAR or 7z file simply due to the fact it is an archive-in-an-archive. Unless the file is opened in an archive program and extracted directly (which would still involve the program extracting the file to a temporary location to retrieve file listings) you would usually have to perform two extractions, one from the bz2/gz compressed archive and another from the tar. So unfortunately, it isn't really as convenient from a Windows GUI perspective compared to the widely popular file formats used today with Windows. Like Zinga says, it's "Too UNIXy" to replace the ZIP or RAR.
