I had to cancel the order that I placed for a 2.7GHz Dual-Core Intel Core i7 Mac Mini with SSD. Recently found incompatibilities caused me to cancel the order. I received an email today from Sonos stating that the the new Mac OS X 10.7 (Lion) release is not compatible with your current Sonos system if your Music Library is stored on your Mac. In addition, it seemed as though there was also an issue with Screen Sharing, and I never thought about Screen Sharing from a Snow Leopard Machine to a Lion Machine. I accepted the fact that Quicken would not work, and I converted to another financial software, but it seems as though there is other software that has incompatibility issues. This site may prove useful to others that are looking to upgrade to Lion and/or the newer technology.

In the mean time I am going to have to wait for the dust to settle before upgrading my current Mac Mini. Bummer.
