nearly a year, and have been doing it two-fingered since October saw the 1.2 multitouch release. Now you Apple fans can get a feel too, with BumpTop Mac newly available. There's a free version for you to try, or a $29 Pro edition that adds support for multitouch trackpads, enabling you to quickly form piles of docs and filter through them. Yes, piles of documents, much like that leaning tower of expense reports your co-workers have been giving a wide berth whenever they walk by. After the break you'll find a video of it all in action, and you can get your free trial at the read link -- assuming you're running OS 10.5 or higher.
