Your advice on the current models is sound. Your predictions on the next rev however, are ridiculous. They still have a while with this design to go. Not every single MBP release is a show-stopper. Your logic also doesn't account for the Mid 2009 MacBook Pro revision which was largely underwhelming save for the 13" Pro introduction. Also, as much as people on these forums want them gone, Apple isn't doing away with the optical drives on their "MacBook Pro" laptops anytime soon as there are still way too many applications where having a built-in drive is hands down more convenient than not. Plus they don't have as much of a chokehold on the software and film industry as they do on the music download industry. Nice try though.
With all respect, you may want to re-read my post. The very first line says it all... this is MY OPINION. NOT what I do know with certainty.
Yes, I agree, the 2009 models were not that big an overhaul. Except for the introduction of the 13" MBP, the sealed in batteries and the SD card slots. Truth be told. There is, however, no logic behind redesigning your machines within one year.
Me assuming the redesign is based on the following:
1. Normal cycles for design overhauls seem to be b/w 2-4years for consumer grade machines. The current MacBook Pro design would fit right into this schedule.
2. Intel and AMD/ATI's 2012 roadmap tells us to expect no big leaps (wait for 2013/2014 for Haswell to be a bigger improvement). Apple, however, likes to sell us their next magical and revolutionary MBP. Do I believe there will be no significant change? Not likely if you ask me.
3. Apple's own marketing: MBA The future of MacBooks. What that means exactly is open to discussion. But it does seem viable, that the MBP will take some features from the MBA.
4. Apple's issues with Bluray and the Mac App Store.
It seems Apple is embracing the digital/online distribution of all things media. First music, then movies, now applications. Also there seems to be an ever increasing move to the cloud. Additionally, REMOVING could be sold as revolutionary. While keeping a DVD drive, but NO Bluray drive would hardly convince anyone.
5. The sources who claimed to have knowledge about the new 2011 MBPs have mostly been wrong. There, however, seem to be numerous sources claiming the above changes. I don't fully believe these rumors were wrong. They might just have been related to a yet-to-be-released prototype or other test-bed.
6. The market.
Look at the MacBook PRO. Emphasis on PRO. Especially the 15" and 17" models are not MEANT for the average Jane and Joe, how could hardly afford it anyway. Yes DVD drives are great features... for watching DVD movies etc. But else? If you are a student of some other form of consumer, who wants to hook it up to the Big Screen or who hasn't got any other TV / DVD player / Bluray player, the SuperDrive is mighty useful. Therefore I don't believe it will be axed from the MacBook (non-Pro) any time soon.
But for the professionals. They don't NEED a DVD burner in their MacBook Pros taking up valuable space. They might want a Bluray SuperDrive for their video editing / authoring, which they will not get. Chances are, however, if you NEED a Bluray drive for your working-life / to make money, you have a stationary machine to take care of that.
But by now... a DVD drive is purely WASTED on a Pro-grade machine.
These here things ALL TOGETHER lead me to believing there will be a design overhaul in the near future. I don't claim, however, that this is or will be 100% accurate.
Maybe Apple pulls a 2008. Releasing an early 2011 model before March, and introducing a new design in October.
Maybe, and if you ask me, most likely they will take care of the redesigning in the 2012 model. Or pull a 2008 in THAT year.
The one thing we know that very few things are ever REALLY certain with Apple. But the evidence that is there, is clearly pointing in the same direction as I do.
