The portable All-In-One segment never really took off with consumers who would rather have a regular tablet. As a result, ASUS has discontinued production of the Portal AiO system.

The Bottom Line

Sep 24 2014 - ASUS offers a much more portable and clean design with their new Portable AiO PT2001 hybrid all-in-one system but it has some significant trade offs.

ASUS markets it as having desktop performance but it is similar to a laptop just like all the hybrid designs and it is hampered by its reliance on a standard hard drive rather than a hybrid or SSD solution. It does provide some more connectivity options with its HDMI ports but has much fewer USB ports than a standard desktop. Overall, it is a nice setup but its doesn't offer enough unique from its competitors.

Review - ASUS Portable AiO PT2001

Sep 24 2014 - The hybrid all-in-one market segment is not a new one and the Portable AiO PT2001 is not ASUS first attempt at it. That could be the Transformer AIO that essentially offered a traditional all-in-one monitor stand and a display that could be docked in and out of it.

With the AiO PT2001, it removes the whole dock concept and instead uses the whole display as a large 20-inch tablet instead. This gives it a sleeker appearance and reduces the cost but it does have some drawback particularly when it comes to peripheral ports. Overall, the design is quite good and really does look like a 20-inch tablet only much thicker which of course makes it less portable than a tablet. It has a kickstand that fold out from the back of the unit when you want to use it in a desktop mode but folds into the back so it can be carried via a ridge and handle flap in the upper portion of the back when used as a mobile tablet.

One problem with the design of the Portable AiO PT2001 is the peripheral ports. With the slim design there is little room for them. This means that it has fewer ports than most traditional all-in-one systems. Placement is also an issue. Typically many of the ports would be placed on the back of the display. If the screen is laid down on a table to be used as a tablet, those ports can be accessed. As a result, all of the peripheral ports reside on the sides including power. This means that when it is used as a desktop, there is going to be a fair number of wires handing off the sides if you need to plug it external items.

The previous Transformer model did not have this issue because of the docking station. At least it uses a wireless mouse and keyboard so it only requires the power cord to be used in its desktop setup.

Since the hybrid all-in-one systems are designed to be used away from a plug, they are of course based on mobile parts. Powering the Portable AiO PT2001-04 is the Intel Core i5-4200U which is dual-core low voltage processor that is popular for ultrabooks and many new laptops. It is not an extremely high performance processor but it provides more than enough performance for basic web browsing, multimedia viewing and productivity applications. The processor is matched up with 8GB of DDR3 memory that provides a smooth experience with the Windows 8 operating system.

For the storage, the Portable AiO PT2001-04 uses a traditional hard drive that provides it with one terabyte of storage space. This is more than more of the other hybrid all-in-one systems on the market but it does have a drawback. Several of the competing systems use either a solid state hybrid drive or small SSD drive as a cache. The result is that the ASUS is not as quick when it comes to loading applications or booting into Windows. Now if you do need additional storage space, there are two USB 3.0 ports that reside on the left hand side of the screen for use with high speed external storage drives. There is no DVD burner due to the size constraints of the design but this is becoming much more common in modern PCs. There is a 3-in-1 card slot of use with memory cards.

For the display, ASUS uses a 19.5-inch IPS panel that has become popular with the hybrid all-in-one segment. It offers nice bright colors and has a very responsive capacitive touch system that works well. The screen is fully coated with glass because of the touch surface and this makes it more susceptible to glare and reflections but this is common for all the hybrid all-in-one systems. One downside is that the display resolution tops out at 1600x900 which means that it does not fully support 1080p video although it can down sample it. One big difference here though is that ASUS has both HDMI in and out ports so the system can be used with an external monitor or HDTV and also be used as an external display for a game console, media streamer or DVD/Blu-ray player. The graphics in the PT2001-04 model uses the integrated Intel HD Graphics built into the Core i5 processor. This means that it has limited ability to be used for things like PC gaming with 3D graphics. It does make up for this somewhat by being able to speed up media encoding with Quick Sync compatible applications.

As this is a portable system, the unit does feature an internal battery pack although ASUS does not disclose its capacity rating. Instead, the company states that it can run for up to five hours when used away from power. In digital video playback testing, the PT2001-04 was able to run for just over four hours before going into standby mode with its default brightness settings. increased brightness levels will dramatically reduce the running time especially with such a large display compared to a laptop. Still, this is more than enough to watch a movie or to do some work.

Pricing for the ASUS Portable AiO PT2001-04 is between $800 and $900. This makes it more affordable than the Dell XPS 18 but on par with both the HP Envy Rove 20 and the Lenovo Flex 20. The Dell XPS 18 is a smaller overall system thanks to its smaller display but it does support a 1920x1080 screen for better clarity. It also offers faster performance even with its older generation Core i5 processor because of its SSD caching. Similarly, the Lenovo slightly edges out the ASUS because it features a nearly identical setup except for the SSHD drive although it has less storage space.
