Looking back at the '06 - '08 MP's, they actually sold for less than their closest PC vendor counterparts. Options could change this, and particularly software. But in terms of hardware, the '09's no longer follow this trend, and the software/options aspect is still similar to previous years (from '06 on).
Keep in mind, I'm used to the software investment well out-costing the system by a notable margin. In some cases, a single application suite can do it.
So from this way of thinking, financially speaking, the MP's are harder to justify for some (not just based on $$$, but the best overall combination of machine + software). It can get detailed rather quickly, and would likely be different from user to user, even if their situations are similar. That tiniest detail could make all the difference.
You made the best choice for a solution for your needs. Quite simple really.
But for some that value has declined (or even disappeared), going by some of the posts I've seen since the '09's dropped. Yet others are still willing to stick with MP's, even at their current pricing.
My only hope is that potential buyers make careful consideration/comparisions,... before they buy, no matter the system purchased. My reasoning is simple:
1. So they get the best system that fits their useage and budgets (ie. best value to my way of thinking).
2. The choices we make with our wallets is the only language corporations really listen to.
Not at all.
To me a computer system (hardware + software) is just a tool, and which ever makes the best over-all solution wins. It's just not likely to be the same for everyone.
