While checking out some of Apples newest toys and accessories, tripped across the iBike unit that uses an iPhone as a digital interface interface / display device. At $150CDN it ain't cheap and some of the reviews posted against previous versions are less than flattering. But the software is available free for download so I did and actually it does look pretty complete and sophisticated. Including a supplementary power source for extended usage.
Apparently the case is pretty waterproof but some people have had issues with the security of the attachment system. Lots more expensive than most basic wireless computers and a lot bigger, but if you're taking an iPhone with you anyway that may be incidental. This has the potential of being interesting but could easily be a lemon rather than an Apple
Any recent reviews with any of the multitasking iPhones?
