Is it worth it to get a macbook pro or macbook + ipad 2

Question

i am in high school and going into 10th grade next year. I have done quite a bit of research and think i have narrowed down my options based on my needs and how much money i have. I am in need of a new computer since my laptop will not make it much longer and i cannot get it repaired (also I want to get a mac because i like them a lot better than any other computer). I need the portability of a laptop, so an iMac is out of the question. My sister recently got a macbook pro for college and seeing the price tag that had for the 13 inch, pricier model, i know i cannot afford an iPad 2 and MBP.
I then have two options:
1) Buy the same MBP that my sister got: $1499 13 inch MBP (with a printer included with whatever i get, if it helps, probably not though)
2) Buy a 16GB iPad 2 wifi and a MacBook for around $999
I like option 2 better because when i go out of town for soccer tournaments i usually bring my laptop with me but i do not like to carry it around the hotel, so an ipad would be great. also it would be ideal for long carrides (which i take often). battery life is also better on the ipad. Whatever i get will mostly likely be my computer in college (hoping nothing bad happens and i dont need to replace it before then). I will not be doing anything heavy so that is where the MacBook is fine. If i go with the MBP, then i will just have to use that and hope for as much portability as possible, although it should not be terribly bad.
The overall things i REALLY need is:
1. Portability
2. Something to do essays, presentations, etc on.
3. Reliability (i guess i mean battery life)
4. Something to take notes on (more or less in college but very possibly in high school as well
5. something that will be easy to do research with when on the go
I think if i were to choose i would go with option 2 but please tell me what you think as i do not know much about how well macs are with portability compared to ipads.
Thanks (and sorry the question is so long)

Answer 1

thank you a lot. one more question i had, would the ipad and macbook work well together if i am just using it for writing essays, making presentations, web, maybe movie editing (with imovie for right now) and other simple things? depending on what i end up doing in college, i guess this would also really make a difference. although as of right now, i feel i will either be majoring in a topic with sports science or something like that (i forget exactly what the major was but i hope to maybe be a physical therapist or something like that) or if i really change my mind i would go for being a video editor (which is where maybe an iMac would come in handy for college and FCP) but as of right now, nothing of that sort. Just basic use. I would love to have the MBP and iPad but that is a far fetched idea. i cannot wait for the iOS5 update. But i guess if i got the iPad and Macbook (which my uncle may be able to help with the iPad and i would have to come up with the money for the macbook or vise-versa) then i would have the iPad before the macbook. Which is fine because my laptop still works enough for me to sync to itunes. but i would maybe bring the mac to school and use the ipad for travel and other things, maybe even to replace my ipod since it is older and has almost no storage left on it. I guess the real problem thats holding me back from the MBP is that i dont have a little more than 1000 to spend all at once and i still want the portability of the ipad. But there really is no substitute for a laptop.
