A work colleague wants a 2.7GHz MacBook Pro with a 5400rpm HDD, but I said go for a 2.3GHz CPU with a 128GB SSD as it'll be a lot faster. The 2.7GHz CPU is an i7, but the 2.3GHz is an i5. The i5 + SSD is £1200, but the i7 + HDD comes to £1300. Both have same RAM and GPU. These are 2011 13" MacBook Pro's. Am I giving right advice?
