Should I get one?

I have a 3 year old powerbook g4 1.67 ghz. Lately, I've been driven crazy by the temptation of buying a macbook pro Why?

1) it's outdated. i drool at the new features and specs of the core duos.

2) it's kinda broken. the latch for the monitor is broken, so it's constantly opening unless i put a rubber band around it. the power cord is falling apart and the power port is warped. the battery barely keeps a charge. (and im not willing to invest any more in accessories usable only with the g4). there's also a distracting dark spot on the monitor

3) i really want to run windows to play games, after all, empire: total war's coming out

4) leopard is acting all wonky, i'm hoping it will be solved by 10.5.2, but i'm not sure. it's really bad, sometimes applications crash each other like dominoes. it would be risky and time consuming to reinstall mac os x, and i may not have the ability to back up my files.

5) i can barely fit my files on the hard drive anymore. i have 35 gb of music alone and i need more space. i dont have the expertise or inclination to install a new internal one.

So all this makes me really tempted to get a new one. Why shouldn't I?

Well for the most part, I'd feel bad asking my mom to pay for it, since i'm just starting college and haven't been able to save up a lot, although i'll pay for what i can.
Also, for the most part, apps run fine and i have enough memory to do my work.

In conclusion, i feel like i could make it work for a while, but it's killing me inside. It's mostly the cost that prevents me. even with my student discount, a mbp will be expensive, and i probably wouldn't be satisfied with a macbook. Maybe i'm just venting, but any advice would be appreciated!

also, if i get one, i'm gonna keep calling it powerbook. i really hate the new name.

 

Thanks for the advice, i'm definitely getting that i should be saving up. Unfortunately, my external barely has enough space to hold system files if i wanted to back up. plus i prefer to have all my music on my laptop for when i travel and for general convenience.
The main reason i want to upgrade is the new features basically.
