Here is my list of things your laptop should have:
* A headphone jack that supports the built-in microphone (conferencing, anyone?)
* The magsafe power connector - my kids are rough on stuff, even my stuff.
* USB ports, perhaps at least one of each old and new plug. As many as you can fit on the sides, cuteness be damned.
* an ethernet plug.
* function keys on the keyboard. E.g. - I use F1 and F6 A LOT in Jetbrains IDEA.
Here are things I could live without:
* an SD card reader
* any particular video plug form, as long as I can hook a monitor to something with an inexpensive adapter plug.
* CD/DVD drive - nice to have, but I understand about space and cost.
This is for work, not a fashion show. It's not supposed to be a tablet. I already have an iPad mini, and want something more, a lot more, in my work computer.
