hi I am a complete newbie to Macs and have finally decided to switch from PCs after years and years of suffering! I have done a bit of research and narrowed it down to two MBP choices - 1. 15" 2.66 7200rpm 2. 17" 7200rpm I cant decided between the two! I have been using a Thinkpad T42p for about 4 years now and even though I paid a *lot* for it, it has lasted me as a good friend. I am a software engineer and not into design, graphics etc. I know the general consensus is that you dont actually need the 17" in that case, however is money is not the issue and I'm happy to pay the difference given I am thinking of using it atleast 3yrs. From what I know so far: 17" - more screen real estate, longer battery life, 19200 resolution, Snow le 15" - easier to carry around, same proc speed, no 19200 I went into the apple store over the weekend, and noticed that the 17" was much 'hotter' than the 15". Can anyone pls list specifically what the issues people have noticed with the 17"? - RAM issues with random beeps? - gets hotter than 15"? I guess 15" has had longer to "mature" e.g. going from 2.53 to 2.66 ppl have reported improvements/fixes with screen flickers, screen leaks etc. I just dont want to be stuck with a 15" for 3 years if I can get the 17" ! thoughts? Thanks!
