I've been using Macs since 1984 (!) and have always hated Windows, but I don't see Apple going in the direction I want, while Microsoft, much as I hate to say it, is... Apple has not released any touchscreen device running OS X, and doesn't seem about to, either. They are concentrating heavily on iOS, and almost all of their photography-related innovation is focused on people who take pictures with their phone (other than as a "convenience scanner" for receipts and such, I'd no sooner take a picture with my iPhone than make a phone call with my camera)! As I look at the last several years of Apple's direction as a company, they seem to be focusing almost exclusively on fashion-conscious consumers instead of creative professionals (I have to admit that I am disgusted with their purchase of Beats by Dr.Dre and their most recent several executive hires being from the fashion industry). There is no serious raw file editing on iOS, and the ARM processors are too slow, anyway. Other than the "trashcan" Mac Pro (which was a step back in many ways), there has been no innovation in Macs for professional use in several years. I'm interested in an SP3 for several reasons - probably the most important is to try photo (and to a lesser extent video) editing on a touchscreen with a pen - it seems a great way to work. Secondly, it seems like a great really lightweight machine for travel - it's a LOT more computer than an iPad, yet a lot smaller and lighter than a MacBook Pro. I don't like the Airs because of low-res screens and limited storage - 1 TB of OneDrive (I'd get it through Office 365 University where I teach) goes a LONG way toward alleviating that concern on the SP3. Third, I really don't use much that is Mac-specific any more (I am no longer using Aperture or Final Cut, having replaced them with Lightroom and Premiere, in addition to Photoshop, which has never had a viable competitor). I use Mail and Safari daily, but am not a "power user" of either one. I don't love Word, but I use it because everybody does - nothing but Word really reads Word docs well! Apart from Mail and Safari, my major applications are either Adobe or Microsoft. Keynote is a slightly worrying exception - does PowerPoint finally have a true dissolve? I'm thinking of buying an i5 SP3, not selling either my MacBook Pro or my desktop Hackintosh for now, and seeing how I like the Surface and modern Windows (who knows where it'll go from here). Any pitfalls I should be aware of? How big a deal is malware these days? Will Defender take care of it if I don't do anything really stupid? I've heard that recent Windows is much less vulnerable than XP? I really can't stand online advertising (flashy ads literally make me sick), so I run AdBlock, SafariCookies and DoNotTrackMe. Are there close equivalents for Windows browsers? I am pretty sure DoNotTrackMe is cross-platform, and I believe there are effective ad-killers for various Windows browsers (including IE Metro)? Is there a good cookie-fixer out there for Windows 8.1?
