Saw this article a day or two back. The Final Comments section, especially the final paragraph is very compelling. I have not seen a strong endorsement like this in a while.
The W700 is admittedly thicker than I'd like. It's comfortable to hold but you can't one-hand it for long and it's best used when propped up against something like your leg or the edge of a table. Haswell should help thin things out - and 14nm Broadwell will put the issue to rest entirely. Even with just Ivy Bridge however, the W700 is the beginning of something special. An ultra portable device that can truly serve as everything from a tablet to your desktop. I don't know that the W700 is an iPad competitor, but it will offer an option for those users who want to consolidate their devices.
Pricing is unknown, however Acer and Intel are currently working on optimizing the design to make it price competitive with the higher end iPad configurations. The slide above has the W700 starting somewhere around $799 and going up to $999. The latter I believe is too high. If Acer can deliver the W700 with LTE, Thunderbolt and a a 64GB SSD for $799 I think it's an easy recommendation.
The onus is on Microsoft to quickly enable compelling Metro applications. At the introduction of the new iPad with iPhoto, Apple talked about the tablet being a great tool for photographers to quickly preview and do minor edits on photos while on location. The W700 and similar tablets running Windows 8 could be that and more, but Microsoft needs the right applications to take advantage of it. The amount of marketing muscle Microsoft is putting behind Windows 8 and Metro apps, combined with the sheer power of tablets like the W700 gives me hope that app developers will quickly flock to the platform to really take advantage of it.
The world is changing and for the first time in years, Microsoft and Intel appear to be the ones leading that change.
