No question. I would become a robot.
There are many reasons.
First- of all is the immortality. So what if you die? You backed up your data. Some friend of yours just places that data into another vessel. Then wham your back in business baby.
Second- is the abilities. You now have metallic hands and limbs and such, thus allowing you to punch a brick wall down. Not to mention your arm going into a missile launcher or an Automatic machine gun. That would be kick ass. FLAME THROWER PWNAGE! Then you have they layzor beams and not to add you could jump higher, run faster, and etc. Sure you couldn't "work out" to get stronger, but you could make yourself more powerful by learning more upgrades to put inside your body. Imagine a robot with a core of lightning that would run on it at times to make the circuitry in your body activate much faster. I could see so many possibilities, plus your only as strong as your intellect, which is awesome.
Third- we can change our appearance at will. Don't like this hair? Don't like this face? Bam, changed. You can only do so much to a humans face, but to a robot you can look like anything.
Fourth- I'm just that much closer to being Quotes RL BFF! =D
Fifth- you couldn't make children per say, no sperm, but you can still do anything else a human could do.
Sixth- YOUR THE INTERNET BISH! GO SEARCH THE WEB THE WAY YOU SHOULD! BY BEING RIGHT THERE IN ITS FACE!
Seventh- you could place yourself inside an alternate reality of your choosing if you ever wanted to just escape the world. A controlled dream if you would.
Eighth- You can be the character in the video game your playing, go inside that world and shoot some zombies. Screw tv, HOLD THAT GUN IN YOUR HAND AS YOU TRAVEL THROUGH THE CIRCUITRY!
Ninth- No sleep, and since you can emit lights you're a walking rave
Tenth- Learning things is so easy, just download. Have firewalls though so you don't get a virus, lulz.
Eleventh- Traveling is as easy as 1, 2, Data transfered complete. Just put your memory inside another one of you somewhere else, maybe later on they will have special "drones" that you could download yourself into in order to simply walk around in it, so you could travel easy.
Twelfth- No deficiencies. Your no longer handicapped, mentally or physically, and your body features will never be completely mutated for life.
Thirteenth- No need to eat or drink, thus no need for waste, thus you will never need to waste any time of your life doing anything
Fourteenth- No oxygen, Deep sea diving and air locked areas here I come!
I can't think of any more, but I know I can...just not now.
