I've been using Ms Project since version 1 a long time ago as well as several other packages that have since fallen by the way side. Yes MS Project is the de facto standard, but this is a clear abuse of a monopoly position in my view. Unfortunately there is no real alternative to MS Project that is also compatible with the file type, but the regulators need to be forcing MS to open up and allow competition. Project is also not complex software, all the algorithms and view types have hardly changes over years, it's just the eye candy that's a bit different and the ability to use a touch screen. If you are a Corporation and have lots of money sloshing around then yes you'll be buying this "upgrade" and the rest of Office 2013. Meanwhile those living in the real world will largely keep away from this software or will be incentivised to go and find some illegal copies - which I do not condone, just highlighting the situation that MS have exacerbated themselves.
This costs £909 in the UK on the Amazon.co.uk site and $1024 in the good old USA on the Amazon.com site. That equates to £657.00 at today's exchange rate; a difference of £252.00. How Microsoft can justify such a disparity in regional pricing is beyond me. I'm a Microsoft Partner and run a small IT firm. Getting my customers to buy MS software is getting increasingly difficult.
