ESX (currently based on Linux 2.4 kernel) VMware ESX is not based on Linux. ESX is vmware that runs directly on the hardware. ESX does use a version of Red Hat as a management console. It has been said that ESX uses Linux to provide some device drivers. I don't know if this is true as the list of ESX compatible hardware is different then the list of Linux compatible hardware.
VMware Workstation (the "for pay version") has a few advantages over the free versions of VMware Player or Server. Essentially workstation has all the features of Server (creation of new VMs, snapshotting, reconfig of virtual hardware) and Player (faster console access) in one package. VMware Infrastructure (ESX) is a more powerfull version of Server. It generally allows for more virtual servers on the same hardware. ESX also supports SANs and live migration of running VMs.
smart ANDarrogant Star athletes are expected to be arrogant. You are welcome to hate arrogant athletes. (I do.) But current culture accepts arrogant athletes, not arrogant smart people. It sucks. That's life. Deal.
Jocks hate you because you're smarter than them. Don't be stupid. Being smart is not the reason people are hated. Being smart and an arrogant son of a bitch is. If you talk down to people they won't like you.
If you want to be liked you need to both gain respect, by being good at sports, but you also need to show respect and be a nice person.
Apple hardware for the same features is only a little more expensive The problem is that often the features of a Mac are not needed. It is a fallacy to compare a Mac to a Dell or HP with the same features of the Mac. Rather, you need to compare the Mac that meets the user's requirements with the Dell or HP that meets the user's requirements. For example if all the user requires is a computer that can read and send email, browse the Internet, and similar light tasks then even a Mac Mini is expensive. To say that the Mini includes WiFi and Bluetooth is meaningless if the user does not need those features.
The last time I checked VMware Virtual Infrastructure 3 had a number of features not found on the Microsoft product such as live migration of virtual machines. I also prefer the VMware management tools. To take advantage of the full VI3 features you should have two or more servers connected to a SAN. This is not inexpensive, but the payoff will be better uptime. Think of it as RAID for servers. Of course you don't need the SAN, but you lose the live migration features. The advantage of VI3 over the free VMware Server is the better performance and management features.
I prefer the VMware tools. They are more mature then Microsoft's. The MS tools will catch up I am sure, but VMware has a couple years head start. VMware also runs Linux better then Microsoft's product.
Because the VMware images are portable across all of the VMware tools, you can develop a server image on your workstation and deploy it onto the production VI3 machines. VMware has a great snapshotting feature. It is great when testing and deploying patches. You take a snapshot of the virtual machine. Boot it in a network isolation mode. Install and test the patch. If it works you either install the patch on the production vm, or just swap the snapshot for the live system. If you time it right there is no downtime.
You may also want to consider XenSource. It is a commercial product based on the open source Xen. The advantages of the commercial product are the management tools and support. Xen is blazing fast.
The only real cost in changing back would be changing back from Mac hardware to PC hardware That is an incredibly naive statement[1]. At a minimum it assumes that a company makes a switch back to Windows almost immediately. Most companies would stick around with a platform for at least a year. Aside from that there are very real internal costs to switching to any platform. There will be costs to reconfigure the servers, retraining for the staff, and overtime or consultants to reinstall Windows. There will be costs just to insure that everything is considered so that there is no staff down time. There will also be licensing issues. If the company does not have a volume license for windows then they are likely using OEM versions of Windows which cannot be installed on other hardware. If they had a volume license then they will need to repurchase it as they likely let it lapse.

Every company I know with an IT dept used a customized Windows install. Even when the IT dept was just one person. I don't see why Linux would be any different.
You can see a difference between an all digital and mixed digital and analog setup. With a mixed setup there are errors (noise) introduced at each conversion step. The analog to digital conversion in particular, as that step is hard, and it will multiply all of the previous noise. These errors will often show up as pixel ghosting giving the picture a blurry quality or a harsh sharp outline. It can be quite pronounced.
The problems get worst if cheaper analog cables are used. Analog signals are prone to interference and the quality of the cables can have a significant impact on picture quality. In an all digital system most (common) interference will have minimal impact on picture quality. The cheapest of cheap cables can be used with no real difference in picture quality. A really fantastic analog system can probably be as good as an all digital system, but it is unlikely that an expensive analog system can be better then a basic, inexpensive, digital system.
Most people with average eye sight should be able to tell the difference between an all digital system and the same system used in a mixed digital to analog to digital mode.
PGP was a godsend to political dissidents around the world, No. PGP like all encryption is largely irrelevant to most political dissidents. A despot will lock up a political dissident just for using encryption. Encryption generally only works for people on groups who have some form of legal or military protection from the adversary.
I use Luks/dmcrypt to encrypt all but boot under Debian/Etch. It was dead simple to setup and seemless to use once I enter the passphrase at boot time. I believe the same can be setup on Ubuntu just as easily.
On a Pentium-M 1.6GHz laptop the performance impact is minimal as the hard drive is already slow.
The problem is that this is yet another technical solution for what is a social problem. As has been shown many times before: technical solutions to social problems simply don't work. Technical solutions can and will be bypassed. The child will disable the software. The child will bypass the software with a live-cd. The child will use a computer elsewhere.
Batteries don't last forever. Lead-acid lasts longer then most. Still 7 years for a lead-acid is considered a long life. While the battery will still work it won't likely charge to full capacity. In colder climates batteries are sometimes replaced every 3 years. Batteries fail for a number of reasons. The liquid boils away, impurities get in, and little shorts form between the anode and cathode.
MacOS X is almost but not quite Unix. To a user the differences are minor and likely don't matter. To a programmer some of the differences are quite big and problematic. As a simple example the filesystem layout is completely different.
All products need an "about" section. It should be fast to load on a modem. You have less then 30 seconds and just a few mouse clicks to grab a potential customer's attention.
Several (western ??) countries have laws similar to Germany's for the procescution of child pornography. IIRC it was Sweden that started with the idea.
As you are British I believe that you will still be fingerprinted and have your picture taken if you cross by road from Canada. It is not TSA playing these games at the airports it is the border guards. They have just choosen to start these measures at airports.

Full disk encryption and file encryption (PGP) defend against different attacks. You need both.

That is disgusting.
In my experience hard drives are the biggest cause of laptop repairs. Especially after the 3 year service plan runs out.

Except a computer that is running 24 hours a day is not a minor contribution to your electricity consumption.
Apple is a systems company. Neither the hardware nor the software can stand alone.
