Well, when mine was working I'd give it a 4 (due to minor little bugs pertaining to running older software on XP, otherwise it was fine.)
But, however, mine is 3 1/2 years old now and I've had the hinges replaced a couple of years ago after cracks started appearing on the silver part near the back part of the monitor shell. Since the replacement, the cracks are re-appearing (I find the plastic Toshiba is using is not as reliable as the older models.)
I recently had to undergo a motherboard replacement, now I appear to have a dead HDD (I'll start scrounging around on eBay for a new one this coming month) and it may have to have the mb looked at again b/c of no display or keyboard recognition showing up.
I had went with a Toshiba due to having a previou one (this one was a mid- 90's Satellite T2135CS) Specs on that one were:
90 MB Intel (pre-Pentium I)
8 MB ram (was expandable to 32 MB)
550 MB HDD
floppy drive
and Windows 95 had been preinstalled (I acquired this one secondhand in exchange for some work on a desktop computer.) It lasted for almost 2 years until it wouldn't even come on.
My current one is a Satellite 1005-S157, which has the following:
1.06 GB Celeron
128 MB Ram
15 GB HDD
56K modem
14.1 TFT display
Intel graphics card (830 M series)
DVD/CD rom drive (modular)
Floppy drive (modular)
Windows XP Pro
When I get ready to purchase another laptop, I may go for a different brand (a friend just recently bought an HP and so far she loves it.) But it seems to me that Toshiba isn't known for the reliability that it used to have.

So as far as the scale from 1 to 5 goes, I'll be generous and give it a 3.
