When you measure the complexity of what today's OS are required to do with the the number of computer makers and peripherals coupled with the endless configurations and software, it's truly amazing that there are so relatively few issues. Not to mention the widely varying skills of the users, it's a wonder nearly everyone on the planet with access to electricity has one. There's not another product that comes even close. It's always fascinating to me that most of the complaints come from IT "professionals", meanwhile my mother just follows my instructions over the phone and she upgrades with zero issues....and prints...and scans....and connects to the internet!
every time you buy something, you vote with your euros. you do realize that your efforts perpetuate bad service from ikea. they haven't staffed/trained their service people to handle the workload and as long as customers are willing to shop there and wait on hold they have no incentive to change. large companies like ikea are well aware of their service levels and are more than aware of their revenues. when the revenues drop....so will your wait times. shop elsewhere.
