Nope, my requirements are RJ45 not a multi-function port. Simple as that. I don't always have access to wifi, and often don't have access to a desk - working in a data centre configuring new kit with a crossover cable before it can be managed from elsewhere. Not all customers have a build area so you have to spend some time in there. In this situation adaptors are just awkward.
If I was buying an Air I'd agree that lack of ports is the price to pay for portability, but a pro laptop should have RJ45. It's inexcusable. Dell, Lenovo and HP all have RJ45 on pretty much everything that isn't an ultrabook. Apple are steadily reducing my buying options. No laptop with RJ45, no matt screen option except for the old MBP, no tower-based desktop. I don't want to move to Windows, but when my current Apple kit needs replacing I dread to think what will be available given the current trends.
Although I agree with you regardign the matte option I still have to ask you this. (and others)
What and how long would you keep something in a laptop? The longer you keep old technology the more limited you become for the future technology (as something old takes space instead of something "better" & "new")
You see, if we take your approach then we would have to also keep Floppy discs or CD drives because some people "might" need them. That mentality or approach limits you in terms of progress.
The term "PRO" doesn't mean all the thing in one package. In fact, some people's expectations about "PRO" means : The LATEST & FASTEST. Which obviously your approach won't.
I'm not dissing you and your needs but I am dissing the way you think about things. What Apple simply does is to put the things they "believe" is the "PRO" label worth it. I hate that they killed 17" and I hate that they can't offer matte option and it bugs me but I can't say the same about ethernet etc. The reason is that if one needs it then the option to use it is there which is something you can't say about matte or 17" option as you simply don't have a solution there. (none!! - unless you switch platform but this is not about that)
I can't remember the last time I needed DVD drive or ethernet. Everywhere I go there is wifi and if that wouldn't be the case I would get the adapter but WIFI si the future (or actually present at this point). Its ok for you to need the port and its fine as we all have different requirements. What is not ok for you is to request that Apple keeps the technology for small amount of people. If every company was thinking the same then there would be no progress or if there was there would be always price for it (ie, when floppy was replaced by cd, if they kept them both in a laptop it would mean a lot of sacrifices. either thicker, or heavier or just everything that "PRO" does NOT deserve.)
Its ok that you need it but please, you have the option to get it. I dont' think its fair that you complain about a little square that has dimensions of 2x3cms (max)
Think ahead and what it means for future. OR think about this. IF Apple and other companies will do what you suggest then who WILL make progress in technology?
AS Bill Gates said: "640k memory will be enough"
And again, I'm not dissing you or your need. Just asking simply to consider the bigger picture rather than yours.
