PSP Cheaper Alternative to the Ipod touch

I am one of those rare people who are what I call bi-technical. I use both macs and pcs , I have an ipod and a sony psp, I am comfortable with both. What I am leading to is that there are a great number of inexpensive alternatives . For students who cannot afford a laptop can use the psp to search the web for information necessary to complete a research paper, find their friends on face book or the current transit schedule. The psp is currently selling for around $165 at Best Buy with a 4 gb memory stick for around $79 you are well on your way to cyberwowrld for a over $200 . I love the new ipod but everyone cannot afford it .
