No, not now at least. In fact, contemplating moving to Mac. I found my Lightroom is cross platform and I can live without Photoshop or use it on the PC if needed. My PC is custom built to my specs for Photoshop primarily but having used IOS on Ipad and Iphone for over 4 years I may decide I want the better integration of the three devices. In any case, I'll wait. I never was tempted by Win 8.
I've been using Windows 10 preview builds for a while now as my main system and I really like it, but at the end of the day I still believe Windows 7 is the best release they had since Windows XP and will remain that way for a long time to come.
I used a beta release of 10 for about a month and liked what I found. But like others I will wait for a month or two before taking the plunge. My son is installing it in a spare box to play with it before he makes up his mind and I will probably follow his lead. I am still happy with windows 7 and am in no rush to upgrade.
