Why do people need MP3 players? That's what a computer's for. Why do people need TVs? That's what torrents are for. Why do people need console systems? That's what emulators are for. If it weren't for me working at a cell phone company, there WOULD be no other gadget I even use besides the computer. My TV hasn't been turned on in months. I download everything I watch! T-Vo can suck it.
PS2 and the MP3. Without my MP3 I would die of boredom when I'm out, and without my PS2 I would lose touch with single player RPGS xD
My favorite is the Palm Treo 650. I love it because with Neeews I can get my daily newspapers, recipes. Also quotes of the day. The other is isilo. Many of the medical text books that I use are using this program.  B)
Electronics, mine would be my ipod and my xbox 360. I get on and play Halo 3/ Smackdown vs. RAw 2008 every day on xbox live. :maha:
