If you are targetting Xbox anyways, it's not too bad to dev with xbox alone. The disadvantages that I can think of are:
- you have to be signed into Live the whole time
- depending on your devlopment habbit, if you are the type of person who writes 3 lines of code, and run it, it can be a little tidius (build, deploy to box, run, exit..etc). if you can dev without actually running the code (just change, build, repeat), then it's not too bad
- if you don't have wireless set up, you have to be tethered to your xbox/switch/router the whole time...
If you plan to get into pc xna game dev, might want to start saving up for a new computer.
