No wonder AT&T is complaining about Verizon's "we have 5x more 3G" campaign when Verizon's 3G is the same as AT&T's 2G (which does have more coverage than Verizon's 3G).

The truth is that the provider's definition of "*G" is what ever their marketing departments say it is. There is no absolute standard of comparison on the marketing front. You have to dig into the actual specs to do so.

I think that there are three distinct "universes" of OS: Desktop (and maybe phones now), Enterprise (support for the Desktop: Exchange, intranet web servers, etc.) and Production.

Solaris is for production and it serves that purpose very well indeed. I think you'd be surprised at the percentage of Solaris use for production use by the Fortune 500 companies. And nothing else is seriously considered except for HP-UX, Linux and AIX, at least at the company I work for (well over half, around 20,000 or so, are Solaris; Linux is in third at around 12%).

I have used all of them and I like Solaris and Linux the most and I find them the most similar to one another by far. HP-UX is very solid, also, but a little quirky.

AIX is the least standard of any Unix-like OS out there, IMO. It is almost like IBM completely rethought Unix from the ground up, but at the cost of consistency with all other implementations.

Huh? In what world did Samba ever replace NFS?
