Apple has updated the MacBook range again, this being the third revision since they were launched last year. Mine is a first revision, and while there's nothing wrong with it, had I waited 9 months I could have got (for the same price that I paid):
- A 2 GHz Intel Core 2 Duo processor, instead of a 1.83GHz Intel Core Duo processor
- 80 GB hard drive, instead of 60 GB
- 802.11n Wi-fi, instead of 802.11g (108 Mbps instead of 54 Mbps)
- Faster writing of CD-RW discs (16x instead of 10x)
But never mind. It's had 9 months of very heavy use and yet doesn't seem to be suffering - the battery is still at well over 90% of its original capacity and everyone else seems to work fine. I guess I'm just envious.

I am in the same situation. 1st generation Macbook user, although I bought the first line of Black Macbooks.
What I am missing out on is 2.16GHz Core 2 Duo, 160GB HD, double-layer superdrive, and the 802.11n wireless.
Still, it is probably the best computer purchase I have ever made. I generally get a good 3-4 years out of my computers and I don’t regret it one bit. I have never had a laptop that looks so nice and fits my style of using computers so well.
The next rev always has a few new things you wish your rev had, but oh well…if I tried to keep up with it, I would be broke.
So far, I am not missing the 802.11n wireless (don’t have a router that can take advantage of it as well as no major stuff like an AppleTV that would really need it).
I’ve long given up on that. When I buy a laptop, I need it. Otherwise, I wouldn’t spend the money on it. So, having it at that particular time and having used it for those 9 months until the better machine came out is much more important to me than any abstract benefits.
Of course, if I buy a machine and the next day the product line gets revamped, that’s reason for anger. Happened to me twice :-(
