Performance his it not a valid reason for not using BES.
Don't you love double-negative arguments? Read the thread again...and take everything in the context in which it was offered. Smaller organizations have to weigh the cost benefits of a BES solution differently than larger organizations. The cost of hardware, MS SBS, BES and a warm body to support that solution is often out-of-reach for a small business. That certainly doesn't mean they wouldn't benefit from the features.
The fact remains...individual and small groups of users need a less costly/less burdensome solution than BES or other middle-ware typically delivers. Unite! and BPS were possibilities, but they lack features. Plus, Rim has announced those products have reached end-of-life. Maybe BES 5.0 will have better choices for the small market...and hosted Exchange is also an option.
And finally, there are users who just don't need BES features...and look to performance as an evaluation tool.
