+1 I can confirm that, just back from a trip and had been debating about getting an W8 upgrade license at the rock-bottom discounted price. Picked up a Sony Viao E-Series preloaded with Win8 Core for travel to match the Nexus 7 as part of the weight reduction scheme for 2013, getting used to the Metro interface a bit but still rather use the Classic Shell to bring up that Start Menu. Going to bump that netbook's 4GB memory up to 8GB as DD3 rams are cheap these days to kick up that 64-bit OS with the $ saved from the upgrade license.

Ran the Upgrade Assistant earlier on the 5 years old Dell D620 that's running w7 Ultimate just fine w 2GB and a 350GB HDD - but registered for the Inspiron 15 that was purchased in 2012, and without even asking for COA or key info, it was accepted & subsequently emailed me with the discount code. Managed to ordered it 30+ minutes before midnight yesterday, and for a token sum - received the upgrade key instantly plus the download link - made an USB stick plus an ISO image for DVD backup purposes, and it CAN be used to upgrade any PC's that meet the minimum specs for W8 installation - it is NOT restricted to being installed on the "qualifying" PC used for the ordering. For personal use, I'm still debating on a downgrade to Win7 on the Sony while preserving the W8 activation image & partition, maybe doing a dual boot on the 750 GB HDD, as I don't plan on wasting the upgrade from Core to Pro.

FYI - apparently, advance users are having luck & success installing W8 on these Dell 600's laptops with boot time of 40 secs. - most likely will apply it on one of the newer desktop now running W7 already. Looking back, I should've get a 2nd. set of key based on the Sony as it would've been an interesting exercise. Taking a bit of adjustment to think of "Apps" while running $S Windows OS - just d/l YouTube Express ... cool, blurring lines into Android & iOS frontiers - except, that it crashed with seconds of launching, so much for being convincing ... as paying beta testers for $S

The intro deal is gone, it's now full retail pricing for most - yikes - heck no way that I would spring for a full license or upgrade at the $200+ tier. For many users, W7 is solid and will be around for quite a bit.
