johnsonrod, midsize market has taken a hit over the past few years and I think a lot of potential Legacy 500 buyers were scared off a bit by the fly-by-wire problems that cropped up early in the program. Now that this market segment is improving and Embraer is on the cusp of getting certification, it's likely that we'll see a swell of orders coming in for this airplane and its 450 sibling.
rajflyboy, when have the fractionals ever routinely operated aircraft at their max speeds? They fly at LRC for two main reasons: lower DOCs and more billable hours for clients. Flying at LRC is a win-win for the fractionals; flying at max cruise on the other hand is a lose-lose for them (higher costs and lower billable hours). The Citation Xs at NetJets or Flight Options have probably only hit Mach 0.92 once -- on a post-production test flight. Speed is a great selling point, but fractional shareowners will never see those speeds due to the higher operational costs. But cabin size can't be altered, so owners can't ever get short-changed on cabin size, unless they agree to be downgraded to a smaller aircraft, which they are compensated for with a reduction in billable hours.
