I guess its only a matter of time until a client starts asking about the Safari update to iTunes and I have to explain about Browser Wars 2. Seems a bit of a storm in a teacup but I was interested to see Apple at least separating Updates and New - thanks to Gary for the breaking Apple news. So how long until we see this dialog then.
Tell you what, I'd be front of the queue. Its turning into quite a talking point with clients. I'm regularly getting asked about iMacs and MacBooks whenever anyone needs a new machine. Even last year the answer was don't go there, the transition for your business isn't worth it. However now, I explain Parallels or dual booting and that you can choose Mac or Windows at startup, its a different proposition.
Take into account the compatibility and stability, the security benefits, the fact your staff can't download as much crapware onto the machines and the big impression Apple design gives to everyone, be it clients or staff, sounds like there could be a business case for switching there.
