My Premium Xbox died on me two years ago....since then ive just been playing on my friends 360. However yesterday i caved and bought a new 360 (instead of going through the hassle of buying a new one.) Since I figured I already had a hard-drive from my old 360 I went and bought the Xbox Arcade. Now I have a question. Im currently in college, and my old hard drives back at home, so itl be a few days till i get it through mail. Since I couldnt wait I started playing Mass Effect again....however im now worried that all my progress will be lost when I put in my old hard drive. Is there anyway to transfer from the arcade to my old hard drive?

Im planning on purchasing a DS...this is the first time i am buying a handheld since the original gameboy (i stuck to the main console systems). However after seeing and hearing all the good stuff regarding DS, i decided to cave in and get one. However Im a bit behind on whats new in the handheld department, so i would seriously appreciate anyones help answering some of my questions.

What comes in the total $129.99 DS package? Do I have to buy a separate memory card or is there one built into the ds? Is the ds backward compatible only with the GBA? Do GBA games perform well on the DS? Thanks a lot for any answers!
