Of course you could always cut open a USB cable, but seriously, why create a mess? If you have one of my USB, Testers it makes it much easier, plus all of the other features it provides. To access these pins you can use a USB breakout or a USB Tester.
For some reason the Nucleo boards don't have the native USB connector onboard, but the needed pins are available for easy access. In the case of STM32, it additionally supports CAN, I2C, and SPI bootloading.

With some AVR chips you can use the Arduino bootloader but most chips come with a DFU bootloader that can support flashing over serial and USB. Therefore I prefer to use microcontrollers that support native USB programming, such as the popular ATMega32U4. Once they are working, I usually want to design a PCB for it. Most of my projects spend very little time on the development board.

But mbed allows you to export your code from the online IDE to the project format for those IDE's.

The unfortunate thing due to the nature of mbed, you can only use the debugging features using a full desktop IDE such as Keil or some of the other free alternatives.
One of the best features is real debugging via ST-Link/V2-1. Each flavor is based on different ARM Cortex architectures such as M0, M3, and M4. They are priced very well and come in different flavors based on your needs. In turn, you end up with multiple buses such as SPI, I2C, and UARTs for your consumption. The Nucleo boards maintain the Arduino footprint but also have headers for the extra pins which gives this board plenty of GPIO for your projects. What sets them apart is that they are 32bit and have, depending on the model, tons of memory and flash. This makes it easy like an Arduino to program and use. If you're unfamiliar with them, they are fast, mbed and Arduino (headers) compatible.
