I saw that, looking for some reviews or Youtube videos to see if it's n00b friendly or not.
Lightroom is not exactly n00b friendly, but the learning curve is nowhere near as steep as with Photoshop itself. Simple things like browsing through your photos and organizing them with tags and such is pretty straight-forward. Messing around in Develop mode can take some practice, but the major adjustments (exposure, color temperature, crop) are easy. Plus, the "auto" functions (auto tone, auto white balance, etc.) are surprisingly good in LR4. A definite improvement over the previous versions.
It's money well spent. Just make sure you back up that catalog!
I guess that's a good deal. Is Lightroom 4 better than Lightroom 3? The "most helpful negative review" of Lightroom 4 at Amazon says it's waaaaay slower than Lightroom 3.
It's a very good deal. On my PC (i7 860, 16GB RAM, SATA II SSD), I never noticed a difference in performance when I upgraded. Lightroom does love RAM, though. So make sure you have plenty of that. Loading the catalog and previews off of an SSD is a boost as well.
