I have been using Ubuntu for a while. Started with 9.10 and recently upgraded to 10.04.
There is obvious disadvantages to using Linux rather than the mainstream Windows. Things like Adobe products still are not compatible with Linux out of the box. Naturally, you can use Wine (Windows emulation software) and install Adobe, but with issues. Or I could use a virtual installation of Windows (kind of like Bootcamp for Macs) and use the software there .. but, why have two OS?
On my laptop, however, I'm not overly concerned with Adobe software. I'm concerned with writing, programming, blogging (which I've not done for ages!) and other things that I can use open source software.
I used to use Windows Live Writer on my laptop (and home desktop) to make posts. Obviously, being a Microsoft software (powerful and free) it wouldn't work on Linux.
I just found, however, a software called Blogilo for Linux. It does many of the same things as Live Writer, and works pretty well. The two biggest differences is Blogilo doesn't create categories nor does it edit pages - only posts. However, for standard blogging, I think this will work nicely.
With that said, I'll be trying to and making more updates to this site. I'll also be working on a new theme to make it look more ... shiny.
So, if you're a Linux user, check out Blogilo.
