Had my iMac for 1 month now and I am truly delighted with the product. Was very close to buying a new top spec PC, but after some consideration, went for a demo at the local Apple Store to see what the hype was about.
Me and the wife considered what we used the home computer for and broke it down into the following:
2) web surfing
3) digital photos
4) creating home dvd's (young family so lots of memories being captured at the moment)
With this in mind, the iMac ticked all the boxes straight away with its pre-loaded iLife package, which after the demonstration and consultation (they really did look after us in the Apple Store). We opted for this one (the 24 inch version was too big), and took it away that day.
The 1st week was painful as we had never used a Mac before in our lives so it was a relative leap of faith, but after using the help files and just going with Apple's extremely intuitive interface, we are now fully productive! I did buy the Mac OSX "Missing Manual" as a supplementary facility and this has been a very worthwhile purchase.
So, a month down the line and we are still smitten by its ease of use and its stunning good looks. Testament to its ease of use is that my 6 year old daughter is flying with it already and is completely comfortable with the interface (photobooth being her favourite application!).
Overall, I am now a full Mac convert and won't go back to PC's. I intend on buying a MacBook for my work soon, but will have to install VMware in order for me to run some windows applications, but I can live with that.
If you are sitting on the fence, take the plunge, we did and have no regrets. You won't be disappointed.
PS - Glossy screen can have a bit of glare when facing a window, but we just moved it!
