I've had IE issues with Evo *and* Revo. Minor things, mind, but still rather critical in the grand scheme. For example, in Evo I had a specific problem with the date picker no appearing at all. The solution for me was to tell IE9/10 to work in IE8 mode. Since upgrading to IE11 I've had to switch to FF permanently, though off the to of my head I can't actually remember the exact cause. I'll try to be more specific later.
In Revo I have a few clients who've had trouble getting things to save properly. I suspect many of the issues have involved MIGX, having thought about it, which I've used successfully on several sites.
Given how few sites I've built, and how many you clearly have, I'm surprised you haven't had troubles. It would certainly be good to get more feedback to corroborate my story, but I suspect few developers use IE.
Tune out here if you don't care about the Windows vs OSx debate. I don't want to hijack the thread.
Regard Apple, I want to make it clear that I do try to stay as open-minded as I can on the subject. I'm hardcore Windows, clearly, but I'm constantly on the look out for genuine redeeming features of OSx. I won't go as far as to say that it's "bad". It's just not nearly as good as Mac users would like to think. Ultimately I believe it all comes down to preference, and familiarity. People constantly tell me how OSx is "more intuitive", but those people are always people who don't even know how to use their Macs properly, whom I often give advice on how best to interpret what they're seeing on their own screens. Perhaps to some degree they're able to bumble along ignorantly with a little more ease, I don't know. There's so little in it, though, I chalk it up to people trying desperately to exaggerate the positive experience they get with the very average software they're running on their very lovely hardware. All backed up by the indisputable fact that when you buy Apple, you're invariably buying premium, when most who buy PC invariably buy cheap crap and get what they pay for.
Of course I mean absolutely no offense to Paul at all, so please don't take anything I say the wrong way - this isn't an emotional topic for me. If one day someone can show me why I should be using OSx after all, I'll gladly concede victory and move over. It may still happen. I like their hardware, I only need an excuse, I suppose.
You make reference most specifically to security. It's a classic claim, and in my experience a classic misconception. You can of course making a compelling argument that people are generally safer using OSx. But that doesn't mean it's more secure. Backed up by the essential evidence that independent researchers have consistently reported that OSx actually has more critical security issues than Windows (don't ask me for references on the spot, but a quick search will reveal enough, I have no doubt. I read at least one article during late 2013), it's worth making an attempt to really understand the possibilities.
I should really make it clear that I accept the possibility that it *is* more secure. Trouble is, while that's not what they're reporting, it's also quite clear that the primary benefit Apple has is that there are so few people using their software by comparison, malware developers simple don't bother targeting them. No bad thing. But that's changing now - I'm sure you've seen the reports that in recent years Apple have finally started encouraging their users to invest in Antivirus software.
I think the truth is that if Apple ever gain a majority market share, then we'd see what they're made of. Then their little empire would start falling down like a house of cards, and they'd have to start thinking much more seriously about security. I doubt they really want it, to be honest, and people certainly aren't all going to start paying the "Apple tax" in droves, so their market share is likely a direct result of their premium nature.
If Apple got that much attention, I honestly believe they'd evolve into Microsoft and eventually people would realise MS are the way they are for a damn good reason - because they're responsible for so much more.
Taking the focus from security, iTunes is widely consider rubbish, though I don't have *much* first hand experience that. Safari - probably the worst browser available, though I'm sure the Windows version is vastly inferior to the OSx version (as with iTunes, most likely). Mac Mail is the worst mail client I've ever seen, possibly excluding Thunderbird which is certainly more capable on paper. Entourage/Outlook is the best mail client, and that's from MS. Fortunately most people don't need a mail client these days, much less OSx users who tend to be of a more... simple variety (in my experience, no offense intended).
Ultimately I think it's a hard sell to get anyone on either side to switch. Except that more ignorant punters with money will be swayed by the premium hardware from Apple, and then search their souls for ways to justify the software, which I reiterate isn't "bad", I just don't believe it justifies itself. While Windows may be a more 'rough' environment by nature, it's certainly no reason to accuse MS/Windows of being inferior. If people understood the situation more clearly they'd understand that there's nobody doing a better job on either side. OSx is what it is and the developers react according to the threats. I wager that OSx is laughable insecure compared to Windows and if all the malware was ported we'd all have a laungh. But what does it matter if there simply isn't any malware? It all comes down to which system you'd rather be using, and I don't think you can really cite any solid reasons not to use Windows.
I use Windows exclusively and I don't have any security concerns. Never pick up malware. I only ever run MS Security Essentials which isn't even rated that highly in comparison to other offerings. I'm an advanced use and I know how to avoid it I suppose. If anything that's one less reason to worry about moving to OSx, which has nothing to offer me in return.
I've ranted too long. Apologies - but I've got to post it now or I'll hate myself.
