Computer woes

I have a seven-year-old iBook, and it's on its last legs...

Every time there's a security update (not as often now, since I can't run the newest version of Mac OS X), and I have to reboot the thing, there's a greater than 50% chance that the reboot will hang at either the grey screen or the blue screen, and I have to do the ol' 3-finger salute to get it to boot up. This runs the risk of hosing the directory on the hard drive...

I have an external HD. The internal HD is only 20GB, and my iTunes music library alone is over 15 gigs. Last month, the external drive crashed so hard the computer wouldn't even recognized that there was a device plugged in...

The original dual-USB iBooks had an interesting design flaw, where the hinge of the unit would after time damage and ultimately sever the power cable running to the LCD backlight. Due to this, I can no longer close my iBook. I got an external monitor last year, which was an acceptable work-around until this morning, when that backlight died unexpectedly...

Plus a host of other annoyances, some small (the c key works intermittently), some large (various bits of the system software don't seem to be working correctly; for example, I no longer have a brightness control. And re-installing the system would run back into the first problem I mentioned.)

*sigh*

Meh. I'm off to drown my sorrows in a bad-for-me McDonalds breakfast.
