I ordered the 13" mbp on the 15th and after speaking with someone from apple they told me that it wouldn't ship until the 29th. They gave me the option of upgrading to the 15", which I would prefer not to do because I like the size of the 13" or downgrading to the base model. So basically I'm trying to figure out if I should just downgrade and have my mac sent out tomorrow, which would involve me upgrading to 4gb ram & the 250 hard drive or should I just wait? I plan on using my mac for web design, video editing, and just daily use. Oh and I plan on playing games but only like Sims 3, WoW, and Myst, nothing hardcore. Is there a big difference between 2.26ghz & 2.53ghz?
