I don't think that I mentioned this but I created a tasker profile that performs a similar function like when I text my tablet to wake up. If buy MP3 downloads at home that I dig and want on my tablet, I can text my tablet to startup the android app "Remote Web Desktop" on my tablet. I then can connect to it over SSL and transfer the mp3's from the comfort of my home to my tablet which is mounted in my car.
This is just another example of the convenient cool stuff you can do with your "CarTab". The remote web desktop, by the way, for me was productive enough and worth purchasing the full version.
