Wow! Finally a comprehensive review of the Horizon 2e!
There are actually three models of the Horizon 2e that I know about:
The F0AS0014US featured here, with an i3-4030u, Wireless AC, and a 1TB 5400 RPM spinning drive.
This is the model sold by most resellers currently.
Lenovo also carries two models that they sell directly:
F0AS0002US, which is also an i3-4030u, Wireless BGN, and a 1TB Hybrid SSD.
F0AS0003US, which is an i5-4210u, Wireless BGN, and a 1TB Hybrid SSD.
Keep in mind that if you want the i5, you have to purchase from Lenovo, meaning you will not get Wireless AC, but will have a hybrid SSD drive.
The model can be easily upgraded with an Intel 7260AC adapter for better Wireless AC speeds.
You can also upgrade the memory and change the internal keyboard/mouse dongle.
Unlike the Vaio Tap21, there are no other internal MSata slots for a secondary drive.
Review is spot on in terms of brightness, audio, performance, and battery life.
Other things to note:
* The Horizon 2e antiglare screen features better tactile feedback than the Vaio Tap 21. It is also a fingerprint magnet, and will leave dusty streaks all over the screen. Lenovo includes a blue cloth for frequent cleaning, as I believe they anticipated this complaint.
* Unlike the Horizon 2 27" model, you don't need to use an external USB port for the keyboard/mouse dongle. This is great as all three USB3 ports are available, which is something that the other portable AIO options don't offer.
* The mouse performed horribly from both a tracking and scrolling perspective. The touch scroll wheel did not work well in my testing. Luckily the internal wireless dongle can be replaced with a 3rd party.
* Lenovo provides good service training videos on opening up the device and replacing modules.
* Audio is tinny and without bass -- It is really a shame. Much worse than the Tap21. They do provide a number of Dolby powered software based enhancements which help somewhat, but overall a major disappointment.
* Aura crashed multiple times when changing settings. It's a gimmick, but good for the show-off factor.
* There are literally dozens of multiplayer games which are included. These are actually great games for kids, and are not easily attainable. If you have kids, this may be a significant factor.
