Review: Apple iMac 21.5in (2015)


Apple updates its smaller-sized iMac with an optional 4K screen, but beware the entry-level model.

Adding a Fusion Drive ups the price to $2,459, but it’s a very capable all-in-one PC package.

iMac brilliant


Decided on Apple, had a PC that takes awhile to start up (by comparison to wife's iPad) plus time taken for antivirus to trawl through! Concern was all excel word and spreadsheets that we have on PC. However no need to have been worried the usb3 port...

Top notch product - the best


Was really easy to set up - we are not great tech savvy people (in our 60's) and if easy for us then it is easy for anyone. Great wide screen and at the entry level we feel it is everything we need. Really love the small keyboard and wireless mouse too.

iMac spot on


Apple set the standard in computer hardware and this iMac is a fantastic piece of kit for the cost. Purchasing through JL was as easy and reassuring as ever.

Good product but not powerful enough for the price


Good product but not value for money given the underlying hardware is well out of date. Performance is not brilliant given the new OS due to underlying hardware

My wife thrilled with her new Computer


We have always used MicroSoft based Desk Top Computers, so on the advice of a few friends my wife decided to try an Apple iMac Computer. She was getting very frustrated with MicroSoft 10. She decided to have a John Lewis recommended Computer expert...

Expected Apple quality


The main issue I have is that I have not been able to access email through the Mac despite contact to the help line. I was told there must be a problem with the browser which I have yet to resolve.
