I've been using an Apple remote since I got my Macbook Pro, and I'm on the whole impressed.
The range is pretty good, and the strength (or whatever you want to call it) is excellent - you can point it any which way and it'll still recieve the signal. It's lightweight and fits nicely in your hand, too. I like the tactile buttons aswell.
That's not to say that there aren't a few issues. I'm not impressed with the shiny white plastic, for example. It gets scratched very easily, and after a few days use starts feeling greasy. The one thing that I really dislike is the lack of storage on the Macbook Pro its self. On the iMac, Apple included a little magnetic bit where your remote can sit. Surely it would have been sensible to include somewhere for the remote to sit, or even shorten it a tad so it fits into the express card slot. As a consequence, I'm about to order my 2nd remote in the 10 days that I've owned a Mac. But hey, atleast they're cheap :p
If you're buying it for frontrow, the chances are that you'll have already used one... and lost it, in which case it's really up to you. If you think you're going to loose it again, you might be beter off with something like a "Sik Rex" (it's a product, honest) but don't expect the nice design or tactile buttons. If bought a Mac without a remote (I'm assuming from eBay or something), it's worth the £15. Particularly if you've got an iMac or a Mac Mini. If you're buying this for an iPod, don't expect the menu button to work. That just about sums it up.
Me? I'm about to order my 2nd. Despite the lack of storage, I think it's the nicest one around.
