My two cents on your trolling....
First of all, the fact that one could buy this today and, as we have done for a decade or so, immediately buy third party ram upgrades, and then find out what was NOT made clear AT ALL on the Apple store website - not possible. So to feel like we're a pro by your standards, we then go and ebay a two week old computer, and take the several hundred pound hit before buying a new one within the month to run the software we use.
Upgradability and customisation has been crucial to the computer using experience. One can keep a mac useable professionally for 4-5 years easily, vs the older 2-4 years Windows cycle.
Two grand is a significant portion of income in a year even if you're doing well financially.
Some of us resent paying 50 percent premiums on ram because they come from apple.
Some of us especially resent the change in the upgradeability of the machines being completely non-obvious when you go to buy this thing from the Apple online store.
Some of us have built screaming machines to use in film and tv productions with these 3rd party extra parts. Some of us prefer the superior SSDs available from other vendors. Or building boot disk SSD raids inside our 17" MPB.
Ebaying a MBP is an exercise in caution, as its the most common magnet for scammers and timewasters as well as legitimate customers. Search through these forums for variations on the ebay experience, even if most of them work out.
As for your last comment about working two shifts, it makes no sense as its the fact that those who want the upgrade paths DON"T want to have to buy the latest shiniest shoes every year, but keep the old ones snappy by changing internals as they come down in cost.
But stay stupid.
My argument was aimed at those saying that the Retina Macbook Pro is NOT a Pro machine because it is not upgradeable and hardly trolling. Ending a post with "Stay Stupid", however, that could be classed as trolling.
By definition, a Pro Machine is a machine capable of helping a Pro do their work at the point at which it is sold which, given the inherent power within the MBP-R, is a given. It has nothing whatsoever to do with upgradeability.
Your first paragraph makes no sense. If youre spending 2k without checking the upgrade options (or lack thereof) out first then you deserve to take a big hit. Maybe youll learn then and not do it again? I mean, youd thoroughly check out a car you bought for as little as 1k, no?, but youd expect someone else to force-feed you every drop of info before spending over 2k of your hard-earned just so you can just buy blindly and not have to check ANYTHING out? O...Kay.
I also agree with your comment about it NOT being properly highlighted by Apple but, yet again, it does not make the MBP-R less of a Pro machine. Spending 2k? Do some research.
Upgradeability and customisation are NOT crucial to making a Pro machine and never have been. Theyre an added benefit on some machines and, if they ARE crucial to your business, as indeed they are to some, then buy a standard MBP or a Mac Pro or sell and renew each year or two. It does not mean that the MBP-R is suddenly not a Pro machine. Its rarely ESSENTIAL to upgrade your machine within a two/three year period, its what you WANT to do, not what you NEED to do, hence the "new sneakers" comment. In many instances, a true pro can make an eight year old machine running eight year old software dance and sing.
£2k per annum IS a lot of money, but as explained it WONT be anything like £2k as you would simply "sell on" the "old" machine. Your comment about eBay can be true, but I did not mean exclusively eBay. There are many other sales or trade-in channels out there and the cost - as I explained - to upgrade will come in at MUCH less than 2k which, to run (or work for) a pro business, should be TOP of your expenditure list and fully budgeted for. Like youd budget for bus fares, petrol, or electricity. If you consider yourself a "Computer-Based Pro" and didnt budget for (varying degrees of) computer upgrades or swap-grades over a 1-2-3 year period then more fool you. Its a primary tool for earning your money.
I agree with the comment on Apples RAM prices but again, it does not make the MBP-R less of a Pro machine. It just, quite rightly, cheeses people off.
You have a CHOICE of machines from Apple, and the inability to "build boot disk SSD raids" does not mean that the MBP-R is suddenly not a Pro machine. It just means that, of the Pro machines currently available, this one is not suitable for you.
As for your "Stay Stupid" comment. A) Uncalled for and therefore, B) Yes... please do. Its entertaining.
