I know a lot of people who have not upgraded to CS4, citing the pricing (especially in light of the current economic downturn). But here’s a warning: if you think the upgrade or purchase price is hefty now, be aware that it only gets worse after 2/28/09. Apparently, the initial price of upgrade/purchase was introductory pricing (from the Latin introductoramus, meaning “it will get worse”). For example, the $599 CS4 Premium upgrade will go up to $799. Complete details on pricing are here.
So if you’ve been on the fence about purchasing or upgrading, now is the time to take the leap, before the price increase. Keep in mind that online catalog sources, such as PCConnection (my fave), don’t discount Adobe pricing, although you can save a bit because you’re usually spared paying sales tax. That’s slightly offset by shipping costs, but you can often save a few dollars. Every little bit helps.
