"Very impressive"4.0 starson by raidi0head
Pros: Amazing HD graphics, integration of iLife software suite
Cons: Some hiccups waking up from sleep mode, screen bezel gaposis
Summary: This is my first iMac. I was a PC user for almost 20 years prior to this purchase and I still have 2 PCs running at home as I complete the transition to Mac. So far, (I've had it about a week) the OS (10.4) seems very intuitive and the suite of iLife software works very seamlessly with each other. The graphics are simply amazing. I've had a few small hiccups with the display not responding when waking up from sleep mode (may need to check for an OS update). I'm also getting used to navigating the PC biased world on my Mac by learning what mac software utilities will help me access windows files. I also bought Office for Mac at the same time because it is the defacto standard for word processing, spreadsheets, and presentations and I couldn't function too well without those. I was a little shocked with the fit and finish (usually pretty high for Apple products) because the bezel around the screen was gapping at the seam along the outer edge which I traced to a iSight camera wire connector being lodged in between the seam. It seems better now with a little prying and rearranging of the connector. Overall, my experience with the iMac has been a very good one.
