I love companies who are going through the effort of scare tactics to take advantage of users. Check out this dialog thrown up by Quickbooks 2006 when it starts:
While I can understand that there may be incompatibilities, this kind of dialog that can't be turned off is a major annoyance. And everything about this dialog screams out - "Don't do it!". Clearly geared at 'strongly encouraging' people to upgrade. Now at the same time I've been using this version on Vista for over a year without any issues.
Let's take a step back here though - QuickBooks is a financial package. It's filebased and uses a single data file for its data storage. How bad could it possibly be affected by Vista? UI issues aside (of which there aren't any that I've noticed) there's no reason that an application like Quickbooks should have any problems on Vista. Yet you get a warning and a nudge to upgrade for another $180 (or whatever it is these days) to upgrade (and no upgrade rebates).
More likely the problems come from the daemon processes that QuickBooks runs. Quickbooks loads a bunch of startup programs and downloaders that are constantly sucking resources. These processes download files in the background who knows where and those probably have issues now under Vista. OTOH, a company like Intuit probably should have been ready for any file system based issues long ago, given that the same environment issues apply to XP when set up with a more strict security policy than the default Admin account logon.
In the past I've been very happy with QuickBooks, which has been a good fit for my business for many years. But a few years ago QuickBooks turned into a monster from hell. Even on my fairly fast dual core machine Quickbooks runs like a dog at the end of a rubber leash - dragging, dragging. Then Intuit decided to do away with upgrades altogether and just makes you pay full price on an update for updates that are usually not adding anything new at all, only making the product even more sluggish than it already is.
It's funny to look back on the history of Intuit which was originally an underdog company and became a player mainly because they got the UI and workflow right above anything. Lean and mean - now look what we have <s>... There hasn't been anything that I've seen in years that Intuit has done that has any value for my business. I've upgraded 2 times in the last 6 years, mainly to get a stable version for the OS I was running. The last upgrade to QB 2006 was probably a mistake as it was an order of magnitude slower than the previous version (QB 2003).
Yeah I can kick and scream, but like many others I'm now tethered to Quickbooks in many ways. I have two of my main business applications that dump data directly into Quickbooks (a royal pain due the fucked up data formats Intuit uses), my accountant uses QuickBooks and it's our means of sharing data and of course there's tons of business data inside of QuickBooks. So while I would love to go a different route, it's at this point a pretty major undertaking switching off QB.
So, yeah when I see a 'friendly reminder' like the above I get a little upset...
