NB: Hope the cheesy wallpaper doesn't cause anyone to think I'm a Maxim reader: it's a top result on google image search for "Ubuntu wallpaper" and I found it too nerdy to resist!
Now that Beta's been out for 24 hours I downloaded the AMD 64 Bit Edition for my Aleutia office PC. This is (relatively) energy efficient box made from discarded parts we've accumulated during testing: an Asrock A780GM-LE mATX motherboard with an AM3 240 CPU (2 x 2.8GHz, 65W), 4GB of Kingston RAM, SATA DVD-RW drive all in this nice mATX case (lower profile but otherwise similar to the one we use in our U6 Userful PC).
You can upgrade to Karmic from within 9.04 by typing:
Alt + F2
Update Manager should open up and tell you: New distribution release '9.10' is available. Click Upgrade and follow the on-screen instructions.
I did this but then it wouldn't boot so I decided to download the Beta version (final version released at end of the month) and install afresh. This is probably best as a major feature of Karmic is the ext4 filesystem and you need a fresh install for this.
These are mere first impressions but the Beta is very polished (think Windows 7 Release Candidate) and makes good on its claims. Immediate benefits:
- Very rapid install time (this is great for system builders like us)
- Boot time is faster.
- Nice colour scheme and very cool bootup screen
- Ubuntu Software Center (in place of Add/Remove software)
- Built-in logic games
- OpenOffice 3.1 (ok not that big a deal)
- New icons (particularly like the swiss army one)
ext4 and other fundamentals aside, it's clearly an evolutionary upgrade. But, like me, you operate in the cloud or have your files backed up, then you might as well though you could wait til RC comes out.
