Is the MacBook Air with 2gb enough ram? What's the limit?

Here's my summary. Serato, minecraft, iTunes. Then I have about 4gb of music and I can have up to about 8 tabs of youtube or any website I can buy stuff off of. (Bestbuy, amazon, etc.) and so. The MacBook Air is basically my dream laptop. Unless you can find a MacBook Pro for the price of. $350 than I'm getting this thing!

It's on the low end for Minecraft, but it might be able to run it on low-ish settings (haven't tried running it with 2gb in quite some time)

They're wonderful laptops and for everything else it should be totally great!
