"Burned" with Lightroom 1.4?
Come on, Adobe made a mistake here, but were able to provide a fix quite soon (1.4.1).
On the whole, LR always was and LR2 also is, one of the most stable and bug free Raw Converter releases of the last years.
Despite of the reported performance issues, LR2 is much better and more stable than any of the recently released RC: DxO 5, Capture One 4, and LightZone 3 (which is the best of the latter three). DxO 5 and Capture One 4 both crashed within 10 Minutes of trial on my machine, LightZone had occasional crashes. DxO 5 did not even carried over all features of the previous version, has still the worst image browser I have seen to date, only excels due to its good handling of image noise. All of these programs had undergone several bugfix releases already, and now mostly work, but for DxO it took 6 months!
LR never crashed at least. I'm not an uncritical promoter of Adobe, but honestly and relatively speaking, Adobe did the best new product releases so far.
That does not mean, that there aren't serious problems with LR 2, but the ones of the competitors, were certainly much worse.
Kind regards
