Fits and Starts
It's almost always tough, when a new player starts making headway.
1) General Motor's EV1 Electric Vehicle
They made under 50,000 of them, got a bunch of metropolitan transit agencies to pony up for the charging systems in public areas like at airports and so on, let the people who leased them have a great time with them for a couple of years, then recalled all of the cars for crushing (!) because "there wasn't a market for them". Despite the fact that literally every EV1 user loved it and that there were outstanding orders for more than 500,000 more.
2) Honda's new Hydrogen Vehicles
Has anybody seen the new hydrogen refueling stations? I haven't, either. I wonder how long these will last?
3) Dell + Ubuntu
As noted above, there are issues with locating and purchasing these machines, built on low-end hardware, resulting in relatively low numbers when compared with MS-installed product lines. Many people complain about how "hard" it is to install 'Nix and how their pre-installed MS systems work great. They have no idea how well a pre-installed version of 'Nix would be, because the distributors don't work at it very hard. Dell could quite easily put together a gaming MONSTER machine with kicking graphics and tons of power (plus WINE for PC gamers, wifi, bluetooth, et al.), and then simply tweak any 'Nix distro they wanted to until it worked perfectly on the machine ... then image that installation, build a bunch more killer machines and clone the image onto them. Doesn't get more simple than that, and it's exactly what they do with a Windows offering.
The new guys have to get the corporations to take more of a chance with them, because it's a tough business decision to spend a ton of money promoting something outside of the public consciousness. Shareholders don't like risk.
On the good side, however, I don't recall any major vendor even considering Linux pre-installed before 2005, so things are moving in the right direction. Maybe by 2010 we'll have a decent selection from which to choose.
