We probably all experienced it as kids - the moment when you realise that someone has got a better toy or a hotter computer game. Or when you realise that one of your friends has been on  a better family outing than you've managed. When that's happened - there's only response - didn't want to go there/do that/want that anyway, preferably with a stamp of the foot.

It's not true to say that VMware's Paul Maritz managed the flounce but the news that VMware is not going to produce a bare-metal hypervisor has all the elements of that childhood flounce.

The company said that it was scrapping plans to produce a bare-metal hypervisor although if it did, it would be better than anything produced by Citrix.;"If there's one company that can nail a client hypervisor, it's VMware, said Vittorio Viarengo, vice president of desktop marketing for VMware - which sounds like the Carlsberg approach to marketing - "we don't do bare-metal hypervisors, but if we did, they'd probably be the best hypervisors in the world."

The company announced in September 2008 that it would produce a bare-metal hypervisor and it's been a long wait. And now, we wait no more. What's clear is that VMware could certainly produce such a beast if it wanted to - it's a smart company, full of smart people - but has decided to go down another route.

I chatted to Citrix's Lou Shipley about this and he agreed that VMware could do it if it wanted to but that it had other priorities."It doesn't have the focus on desktop virtualisation that we have, they're pretty much concentrating on data centre and servers," he said.

That's certainly true but what I find harder to understand is why VMware went on pretending that it was interested in pursuing bare-metal hypervisors - it could certainly mount a cogent case against them (and did so) but then why, having dissed Citrix's approach, did it say that it would produce its own - but better.

Customers like choice: Citrix understands this well, the company takes pains to point out that it has several approaches to desktop virtualisation and it would have served VMware well to have provided a choice too. No-one can really cavil after the flurry of announcements from VMWorld - VMware has certainly presented a clear vision going forward but one wonders how seriously punters will take promises of future products again.
