Just because Apple sells items with a few options doesn't mean every other company should.
I'm sympathetic to this argument - there's always the oddball page in the configuration process that doesn't make sense, like the not-actually-selectable "Selectable SIM" on the current page for the T430. But the number of choices that actually don't make sense isn't that high, and the wifi adapter is not a good example. Which is "the good one"? The one with a working driver for someone's oddball OS, or the one with 802.11a support for someone's legacy network?
Do you think Lenovo should do away with one of the two palmrest combinations on the T430, and if so, which one, the one with the fingerprint reader or the one without?
You would if you knew what the chip was from sources other than the ordering page. Owning a model already is an obvious example but if I wasn't so lazy I could probably dig up the model spec book, grab the FRU of the card and google up the specs based on that.
