I recently upgraded from LR3 to 4 and agree with other comments about it being a big step forward in capability, however I have found that it is noticeably slower on my laptop than LR3 was - to the point of being really irritating. I can find no other laptop issue that might be causing this and I wondered if anyone else had experienced a similar problem?
BTW, a possibly daft question, but I assume it is OK to delete LR3 after installing the upgrade?

 It is, howevger, not for everyone as it has a very steep learning curve. It took me several weeks to suss Lightroom. But I then had that light bulb experience and many others describe the same sudden feeling of - wow, I get it and you never look back.
