Let Adobe's 'sneak peek' video speak for itself.

After using Ubuntu 8.10 for 3 months, I've decided I do not like it. Here are the reasons why:

1. I miss Photoshop - 'nuff said, really. I've been using Gimp a lot, and it is powerful I suppose, but it's no Photoshop. Granted, I've yet to get WINE to work with my version of Photoshop (CS3), which unfortunately GIMP does not support well (slaps forehead). Not being able to run Photoshop is a good enough reason to avoid Linux to my mind. Photoshop, see, is more than just an 'image editing software'. It is a religion. The ability to quickly and efficiently edit and create images for use on web or print automatically puts you on a higher level in the web publishing world, and anything else is (I've realized now) is a step back. For the past 3 months using Gimp, everytime I need to create or edit an image I've felt myself pining for Photoshop, and the feeling has not waned since.
2. I miss shortcut keys - In Windows you can assign shortcut keys to frequently used applications by right - clicking the icon on the Desktop then Properties > Shortcut Tab > Shortcut Key. In Linux, not so much. I found this howto but met only limited success with it. Shortcut keys is a wonderful performance enhancer and I navigate my way quickly around Windows by memorizing the shortcuts. Same with Windows apps, I have tattooed in my brain shortcut keys for everything from Photoshop to WinAmp.
