Office 2007 and Vista both perform differently on many systems, such as Thinkpads vs. Latitudes, with default installations using top end hardware right out of the box. That’s not a blanket statement.

I’ve seen tests performed on several different manufacturers systems with installations and benchmarking performed in unison. Sometimes you could see a big difference just by changing out the brand of DIMM’s. But I tend to agree with keeping Vista and Office 2007 out of large enterprises with inconsistent hardware. Unless you’re willing to standardize the environment for supportability.

Funny, and there I thought blogs were meant to be the place to express opinions and provide advice. Why is it suddenly a blanket statement and thus bad?

For what it’s worth, I have Office 2007 on two machines. On my much-lower-speced Fujitsu P1610, Outlook 2007 is OK. On my high-end IBM/Lenovo T60 with a Core 2 Duo and 2GB of RAM, everytime Outlook checks for e-mail, the whole machine comes to a standstill. I’ve tried every fix there is and nothing works. Hence, I’m sure Vista/Office 2007 is fine on many machines, but knowing that it can take down some high-end machines for no clear reason, how could anyone in their right mind recommend it without reservation. Outlook 2007 still behaves like a beta program. Fine on some machines, awful on others. If I told you a plane yoiu were going to get on had only a 1 in 10 chance of crashing, are you telling me you wouldn’t choose to drive instead?

Not just him!
