My first ever imac has just arrived. Day 3 of using the MAC, this is my first experience of a MAC, although I bought my wife one 18 months ago. (now she wants a 27" screen) 27" i5 with 8GB Ram and SSD/ 1GB HD and Trackpad. I have moved from an old 3GHz single core with Hyper-threading, 4GB ram on windows XP, RAID installed for files not OS. (Recently re-installed everything so a fresh install) also two 17" monitors. My wife would be surfing the net and reading e-mails by the time my machine booted and logged in. So anything I bought, would seem fast. First impressions is WOW, it is a thing of beauty. No problems, no yellow tinge, no HD noise, no dead pixels. The screen is not too big IMHO, I use a 30" at work, so maybe I'm used to the size. Application and start up is lighting fast, I haven't pushed this machine as of yet, but I downloaded a trial of photoshop which opens up in under 2 seconds, editing 16GB raw photographs is extremely quick. I have also bought office for MAC (some habits are hard to break) all these apps are very very quick. The trackpad takes some getting used too, not there yet. I'm struggling with the equivalent right mouse click, just doesn't seem to flow, have tried both settings bottom corner or two finger secondary click. Sometimes I also zoom in and out on webpages by accident, I will persevere though and probably stick with it, mouse is at hand just in case. I miss the number pad etc on the keyboard, maybe switch to a wired one, not sure yet, but I like the lack of cables. I have been geektooling the desktop, very nice app, I like the logs and resource monitoring in text format very cool. I have moved my folder to the 1GB HD, I thought that this would be better in managing my SSD drive. At the moment waiting for a 2TB WD firewire HD for backups (hope this is the right choice) Still playing, still discovering, but I am a satisfied customer, no complaints.
