Ubuntu vs Windows
Ubuntu vs Windows
You're weighing options between Ubuntu and Windows, missing Windows but craving Adobe Photoshop. Consider what matters most for your workflow.
For this purpose you can rely on Wine. Based on your requirements Wine should handle the job well. In the worst scenario you can still dual boot, and with SSD speeds you'll be ahead. I require no more than 30 to 40 seconds to change operating systems, and most of that time is spent in POST rather than real OS startup (it reminded me how much I wished for a 512Gb SSD under 150 euros).
Wine is a tool that enables running Windows applications on Linux to some degree. It acts as an intermediary, translating and forwarding Windows commands to Linux. You can use it to set up your own Photoshop installation on Linux. There are utilities available to assist with configuring Wine due to its complex settings. PlayOnLinux may provide guidance for this process.
