Buy a ~$300, AMD-based asus, lenovo, or whatever laptop isn't too shitty and is on sale at best buy/staples/wherever. Don't let them scam you on the warranty. Also buy a half decent SSD - crucial M4, etc.
Pull the HDD from the laptop right away, and keep it in the laptop box. Shove in the SSD, and install a mexican version of windows 7.
Or people who want to run shit that works well under linux, but not windows. I use a Fedora desktop for embedded system development, because running gcc/eclipse/gdb/etc under windows is an exercise in frustration.tsrh
Linux desktop is awesome for people who force the words out of their mouths.
