My recent experiences mean I find your poll too triggering to complete.
I should have had a "you insensitive clod!" answer.
My boss phoned this morning to say, "If anyone asks, Vista is officially a pain in the arse."
I did find a script that "de-Delled" XP boxen quite effectively...
However the Vista installer is much faster than XP's, and you can walk away from it. I'm looking at building myself a custom slipstream disk with Vista and Office images.
Your first sentence half-triggered the bet with myself -- I anticipated that someone would link to it. It used to be called "Dell Decrapifier", but is now called "PC Decrapifier" for legal reasons. It's available free from http://www.yorkspace.com/pc-de-crapifier/In version 1.7, from January 3rd 2007: " I have not yet tested this on Vista. Theoretically it should work, but I’ve had one report that it did not run. Hopefully I’ll get access to a Vista machine soon to test. (There’s no way I’m upgrading my personal machine)"
I use Macs as my desktop and laptop machines, and Pete uses Linux. When I absolutely *have* to use Windows (which I do for browser testing, so all the bloody time), I use a Virtual Machine which runs W2K. Which you left out of your poll ..
I have a Big Man who buys my new computers for me and sets it all up ...
My computer count includes anything with more memory and CPU power than my first PC, which means it includes two phones and two PDAs.
And your PVR and your washing machine and...?
I included my phone as well on the same basis, but did not include devices that I own but don't use (this theoretically includes a SE Z1010, a Palm TC, a Z88, a BBC Micro, shares in an Alpha box and some other bits and pieces too numerous to mention, and a broken Ti Powerbook).
I only have two windows devices - a PC I use almost exclusively for gaming, and my phone, which I am getting increasingly annoyed with.
I did warn you about the Universal. The Hermes (the little slider keyboard) is a better radio device. HTC pretty much threw the Universal together to get a 3G into the market quickly.
Indeed you did, though its mostly WM5 and its flakiness, especially in talking to Macs, that's my main annoyance. I still like it as a 'mobile word processor' and am tempted to retain it in that role. I don't think the Hermes keyboard would work for me - it seems just too small. So current plan is to junk Orange unless they come up with a *much* better mobile data deal at the end of my current contract, and move to T-Mobile with Web'n'Walk and a (free with contract) smaller device to handle voice and data (say a SE M600i but their whole range will have probably changed in a month) while I can still use the Universal to type when I'm in planes or where I can't use a laptop. Data transfer then won't be an issue as i won't be trying to Sync stuff, and can just use my USB/SD card....
But that's probably all more information then you need to know! Sorry for rambling!
I have no personal experience of Vista boxes, so my comment was based on the experience of a colleague who has used it (in beta). My experience of XP boxes may be somewhat skewed by the fact that doing software builds from scratch is a small part of my job description, though these days I'm more likely to be building a Solaris box than a Windows one, and the Windows box is more likely to be W2K or W2K3 servers.
Our CIO was complaining last year that the moment was fast approaching when Windows 2000 would be out of support, and we really ought to get XP. I guess that's never going to happen now.
I assume MS Inc. had decided they had already just about got the maximum revenue out of companies buying XP because W2000 had expired.
I was going to tick "I have commented" and then not comment.
Instead I have done it the other way round.
P.S. What are these "windows" of which you speak?
The shiny new laptop is running Vista.
When my father first came hope with it and announced that it was no longer possible to buy a Windows machine running anything else, my face fell and I decided that I'd wipe it as soon as I could and run the thing off Ubuntu.
But actually, after having been using it for a few days, I think I rather like it. It's growing on me, and fast. It's a lot like the current Mac OS, actually, and it's fairly fast. And you can make it pink. And I do really like the new sidebar thing. And I think I'm going to keep it.
I have heard all sorts of evil conspiricy theories about it, though. Big Brother Gates Is Watching You and all that.
And I never really liked XP...
The main problem with the poll is that it is very black and white, On some machines I have Linux, on some I have software pre-installed, many run other OSs. Counting up the computers is a difficult task, I clicked 20 (maybe could have ticked 30?), but had the question been how many are in common use it would only have been about 6 or 7.
While I own at least 8 computers, only 4 of them are in more or less daily use and it's quite likely that there are more than 4 in the loft. :-)
I included my computers, Julies computers, the work laptop and the PDAs, but not phones. We are a mac household. We have 2 pcs for playing games (though I have plans...) and three macs for work and communication and watching stuff purposes.
I'm getting a new work laptop, but they plan to wipe everything it comes with and reinstall the company's standard installation which is XP SP2, Office, Lotus Notes and various other bits and pieces. I'm forbidden quite strictly to install anything on it, but they did put firefox on when I asked.
There's no box for "I would do something intelligent but I haven't a clue how" This is the function of husbands/boyfriends.
Where's the ticky box for "Win2K was the last decent Windows worth bothering with" (OK, 2003 for servers).
Anything new is getting Ubuntu.
What  ramtops said. FWIW, the count here currently stands at: OS X - 3 linux (Ubuntu) - 2 W2K/AS - 1 linux (TiVo) - 1 linux (Axis webcam) - 6 plus one scratch box in bits, currently with ubuntu and XP hard drives in it, and various VPCs on Mac's box and VMware images on the two linux boxen running W2K, XP or W2K/AS. No Vista yet. oh, and three linux servers at RedBus :) |
