Convertible / 2-in-1

Iterative. The Surface Pro 7 doesn't bring enough to the table to warrant a whole digit upgrade over the Surface Pro 6. Unless if you really value the integrated USB Type-C port or Iris Plus graphics update, last year's model will suffice.

The Clone Wars. The UBook Pro offers high-end looks with low-end performance for a mid-range price. If you can get past the slow Core m3 processor, then you'll find the super-bright 12.3-inch display and three USB ports quite useful when compared to the dimmer and pricier Surface Pro.

Versatile. With the IdeaPad C340-15IWL, Lenovo delivers a well-equipped 15.6-inch convertible, which also offers very good battery life. The IPS touchscreen display can be operated with your fingers as well as with the Lenovo Active Pen 2, which can be purchased separately.

Elite convertible with a matte SureView screen. Convertibles offer more flexibility than regular clamshell notebooks. Business convertibles like the HP EliteBook x360 830 G6 offer even more flexibility than consumer devices. With plenty of features & high-quality components, the HP EliteBook x360 830 G6 is a successful convertible, as there are barely any weak points to this HP laptop.

The Intel Athena Poster Child. With mobile AMD Ryzen finally catching up to Intel's long-running ULV Core U series, all eyes have been on Ice Lake and Comet Lake-U to see how Intel would respond. Pressure has been on Dell to knock it out of the park with its second generation XPS 13 2-in-1 especially since it is the first to ship with the Ice Lake Core i7-1065G7. The flagship convertible mostly succeeds with a few caveats.

Decent home convertible. Lenovo's IdeaPad Flex 14API features a Ryzen 5 APU, dual-channel RAM, and an NVMe SSD. In addition to finger input, its IPS touchscreen display also supports the optional Lenovo Active Pen 2.

The changing business display. With the Dell Latitude 7200 2-in-1, the Texan manufacturer has a competitor for Microsoft's Surface Pro 6 on the market. Especially corporate customers should be impressed with features such as built-in LTE. The design-related instability of the keyboard represents the biggest disadvantage of this Dell laptop.

Too expensive. The PhilBook Max is a 14.1 inch convertible for just over 400 euros. The equipment is fine, but the manufacturer XIDU unfortunately relies on a dark display and a slow Celeron processor.

Eye candy. HP's Spectre x360 13 is a premium compact convertible that is powerful enough for day to day tasks and challenges, and it is equipped with a highly reflective 1080p display that could have been brighter.
