Should i buy mobileme or fruux? That's the question. No question. The answer is fruux.
Great features, very easy to use, much less expensive, ok there is no webspace, but you can get webspace for free at every corner in the web, so the only problem you have is to synchronize your devices. Synchronize with fruux is very easy. Install the preferance pane in (all of your macs) the system control (very easy, you can download from the fruux website), create an account and you can start at the moment.
The support is perfect. If you have any problem, write to the guys and they are working hard to solve the problem.
Fruux is one of best and important little helper in mac universum.
Fruux gets a full buy recommendation.
