1. You can't just ask people around you and use that as evidence. That is not a legit means of polling. How many people? What kind of people? Is there possible bias in the survey(such as using a term like "big screen" instead of home console)? Are you only asking people you know? And for that matter, did you even ask?
2. What does it matter that people play casual or hardcore titles as long as they are playing? System sellers are both hardcore and casual.
3. My answer actally says that they can replace computers and phones. There are trade offs, but no different than using a phone as a computer. The Vita will be improving in functionality over time.
4. I mentioned the memory card price but I forgot to include that inflation has risen since the PSPs release. The Vita is not as expensive as everyone has been told to believe. The memory card is probably to blame for this. When the price was first announced it was received with praise. When looking at the hardware the price is also very affordable compared to other products with that capability, such as the iPad 3.
Before the PS3 everyone was nice to me :(
