Lack of RD, or lack of waste?
The thing is, that if HP invested more in R&D, would it have amounted to anything?
I saw a posting from the Personal Computing division complaining that their R&D budget was only 1.5% of revenue, and that of course they wouldn't be able to put out an iPad competitor at level. But would they have been able to do it at 2.5% or even 5%? Probably not.
The frontline HP staff can complain about the lack of R&D, but would they have delivered anything worth buying, had they been given the money? Seriously, of all of the company's in the world, does anything think that HP has the design expertise to make an competitor to the iPad that would have made money?
As far as HPUX, that ship sailed years ago. It was already dead when Carly took over. Too late to revive it now. HP was doing its "Windows NT is the future" thing for a while, and transferred a bunch of VMS tech to Microsoft, as HP hoped to offload the OS R&D to MS.
And NonStop? Seriously? Yes, great engineering, like 10 years ago. But an underpowered architecture today. Might as well buy the IBM crack, and get a mainframe. At least IBM mainframes are fast, and scale to huge workloads. Probably would cost the same, and at least IBM has a proven track record of support mainframe sites. Talk to a VMS user, about their confidence in HP.
