I had the original iCurve until recently when my flatmate managed to somehow break it on the way back from a DJing gig - I was crushed as my trusty original iCurve had followed me halfway across the planet in various backpacks and cases and survived it all, yet on that fateful day it seemingly met its match. Needless to say I was quite disappointed to find that Griffin had discontinued it only to bring in a new, less visually pleasing model... After hunting around for various alternatives, and also reading of others' mishaps with the original (i.e. laptops falling off their stands and ultimately meeting their demise) I decided to bite the bullet and buy the iCurve 2 (original name huh?!?). I must say in person it is nowhere near as ugly as it looks from the online pics and, although I never had any problems with the original, find it to be even more reassuringly rock solid - and as a DJ I had the original curve in some precarious situations over the years!
In summary - can't recommend it highly enough, you won't find a better alternative for overall reliability and also elevates your Macbook/Pro to the perfect height to complement a second monitor or just prevent a nasty dose of neck ache if you spend a lot of time looking at your laptop screen as I do being a Software Developer. The one other thing it has that the original didn't is the ability to disassemble it at a moments notice and neatly pack it away into its constituent parts which again is a massive bonus for those frequent Macbook road warriors.
