Well, for corporate customers, at least.

It’s no secret that Vista sales have been sluggish, with many people (and most companies) preferring to stick with Windows XP for now. Retail sales are pretty much Vista-only, though, and online dealers have a strong preference for it as well.

At my company, application compatibility has been the main reason to avoid Vista (as opposed to Office 2007, where “user pain” tops our list). If all their apps and peripherals worked, I think most of our users would quickly adapt to Vista, and prefer it over XP.

Until that day comes, we’re sticking with the XP-based models in Sony’s SZ and BX series, which continue to deliver excellent performance and stability (one motherboard failure in 20+ machines, quickly repaired). I’ve been casually keeping an eye on Sony’s lineup, on the assumption that when the existing supply of XP-based VAIOs runs out, it will be Vista time.

Maybe not. Today’s press release from Sony Japan only has assorted versions of Vista on the A, F, and G series, but still offers XP on the brand-new widescreen BX’s. The BX series is still completely absent from sonystyle.com, but now that the new model has been announced in Japan and Europe, it should show up soon here.

Sadly, all recent models in the lightweight SZ series (beloved by our non-Mac-using executives) are Vista-only, but unless we hire a lot more execs soon, we’re in pretty good shape there.
