Yeah, the SoC boards a nice. So much of what you want to do on an FPGA these days requires the use of a processor anyhow, you might as well have an actual hard block instead of a NIOSII or whatever. We use DE1's at my company as the FPGA analog (pun not intended) of a Arduino Uno, for when we want to do a quick test of some part of a design in hardware, or want to stick the device into something but don't want to tie up a high end unit for something trivial.
Be aware that the DE1 has pretty limited resources for somethings. For exmaple, the on-chip memory can get tapped out pretty quickly when doing embedded applications, and it has less I/O and less RAM available off-chip.
Also note that the DE1-SoC actually uses a Cyclone V device, whereas the original DE-1 uses a Cyclone II, a nearly discontinued chip that is a big step down.
Intrigued by FPGA's capabilities, when checking out my classmate's profile http://orangesorter.com/, I started looking into some development kits to learn.
It has an ARM processor on the same chip as the FPGA, which I've found to be incredibly useful.
If you don't want the ARM processor, the regular DE1 is somewhat cheaper: $150 or $125 w/ student discount.
