I’ve been a Windows user since the mid-nineties and I’ve used pretty
much every version of it starting with 3.1. I only skipped ME and (for
now) Windows 10. I switched to Lubuntu a few months ago and it went surprisingly smooth.
The Linux distro that I recommend to people coming from a Windows background is Lubuntu. At least for me, it made the switch quite easy, because everything looks so familiar. Plus, it’s the fastest OS I have ever used. Booting into Lubuntu and shutting it down takes a few seconds.
For those who want to do image manipulation, I’ve been told that Krita is quite intuitive for people who come from Photoshop.
The only Windows thing that I really, really miss (and that seems a
bit ironical) is Notepad++. Although Linux is written by developers for
developers, apparently the Linux community hasn’t come up with an editor that is as easy and intuitive to use. There are no doubt decent enough
editors for Linux, but they are no match for Notepad++ in terms of flexibility and ease of use IMO. It runs on Wine, but for me the font resolution is a real problem.
Just my 0.02 $.
