While I consider myself an early-adopter, at the same time my approach to major computer upgrades is one of caution. After all, I can keep working safely if I let the rest of the world test the new software and operating system upgrades for me.

I have a client who was not so cautious and even though he is a home user with personal needs rather than the more demanding business requirements, it was a headache for him when he updated to the latest Apple operating system, Lion.

Two issues created a problem for him:   Quicken and iPhoto.  Quicken 2007 and earlier will not run on Lion (OS 10.7) and unless you have the latest version of iPhoto, you will feel a heart-stopping jolt when iPhone is simply gone after the upgrade.
