Buying A Tablet Computer Or A Laptop

Hi techies,

I have an issue i need assitance on from you guys that are knowledgeable in IT. I asked my friend to get me a laptop but what he got was just not it at all as in it was very clear that it had been used and even over-used. He's now trying to offer me an HP  tablet. The xtics i got from the properties are "HP Genuine Intel(R) CPU T2500 @ 2.00GHz 997 MHz. 504 MB of RAM." The tablet as i'm sure y'all know does not have CD player though i was told i could buy one. It has Intel Centrino Duo. It is fairly new. It has facilities to connect with blue tooth also.

What i want to know is what is a good price for the computer and if i have to get an external CD player and connect it to it, can i get one that is CD/DVD RW and what price can i expect to pay for the external CD player?

If there are any features you want me to check, just tell me how to go about it and i'll communicate back to you.

I'll really appreciate your suggestions as i have to decide sometime next week if i want it or not.

Thanks all.
