My current Macbook Pro is fine - the new models have slightly more horsepower but I don't feel mine is lacking. If there was a model with more than 16GB of RAM I'd be more tempted, but alas. The lack of ports would actually make it a downgrade for my purposes. There's just nothing particularly exciting in these new models. There's also nothing wrong with them, but they are getting a little long in the tooth.
