I found some places which sell computers in the US that have Ubuntu preloaded but not in the UK. Can you buy computers with Ubuntu preloaded in the UK? Thank you!
DELL sells Ubuntu preloaded computers in UK also. Check this url:
To ensure the availability in other countries, you may check this url:
If you could't find your country in the list on above url it doesn't mean that Ubuntu preloaded systems are not available in your country. For example I bought my lap from India and obviously it is preloaded with Ubuntu.
Linux Emporium is one of the oldest linux hardware suppliers I think.
Dell probably sells a netbook with Ubuntu too (but you might have to look on their "business site" to find it).
And I'm sure there are also several small shops that will sell you computers with Ubuntu on request.
Here is all the places the company ZaReason ships to: http://zareason.com/shop/International.html
They sell Linux OS on hardware and gear. I have never tried one of their machines however I have only heard positive things through reputation.
Have a look on Amazon.co.uk for computers and laptops with Ubuntu pre installed.
Also check out uMi computers website is www.umipc.com for preinstalled computers and laptops.
