New 15" high end vs Old 15" mid end

[lukielala]

Should I trade in my old 15" 2.66 unibody mbp for the new 15" i7 model??!?!

The temptation is so huge! I bought mine only like during February this year.

Any comments?

Depends what you are going to go for.

If you were going to take advantage of the faster CPU, the longer battery and maybe go for the high-resolution screen then go for it.

Depends what you need it for and how much you are willing to spend from when you sell your current MBP.

How much percentage is the speed increase about anyways? I'll definitely love the longer battery life!
