The prices Adobe are charging for the new suits to customers outside the USA and Canada is really quite something. Looks like they are confident that they command the market and with CS3 are prepared to milk it.
Some healthy competition for Adobe would be a good thing all round and perhaps with these new higher prices it will encourage someone to have a go.
I will be upgrading myself because I have to, others must look at the (small) new features list and decide if they want to. There is a sting with this though as Adobe are tightening up on how old products count in upgrades and you may find yourself missing out on the upgrade price on CS4 or CS5 if they do contain useful additions.
