What is the general consensus with the Novation Launchpad vs Ableton Push?

I was thinking about getting a Novation Launchpad just to play around with considering that they just came out with the Launchpad S and the old ones are selling for only $120 after rebate... however, seeing as the Ableton Push has more functionality, I'm wondering whether I should get one just to "play around with" as I am not really super serious. I'm not sure if the extra expense is worth the functionality but fear that I may at some point develop an interest that will outgrow the limitations of a Launchpad. I'm sure the resale value of the Push is a lot higher in percentage returned than the Launchpad too. I don't know. What do you experts who know more about the products and their limitations think about each product? I don't even know what I want to do yet... maybe a little bit of making music... maybe a little bit of mixing and mashing music.
