6 Reasons Against
Does Not Have a Full-Size Keyboard
The Zbook 15 does not have a full-size keyboard, unlike most of the other comparable spec portable PCs that were released more than two years ago which have a full-size keyboard.
Does Not Have a Touch Sensitive Screen
Most similar spec portable PCs that have been around for around the same time as the Zbook 15 do not have a touch sensitive screen. The HP Zbook 15 is no exception to this as it too does not have a touch sensitive screen.
Only 10 Mbit/s Ethernet LAN Data Rate
This notebook PC Ethernet LAN data rate, which is typical of many notebook PCs of a comparable spec and age to it.
Only 32 Solid-State Drive Capacity
The Zbook 15 is a 32 gigabytes solid-state drive capacity laptop. Most of the other laptops that came out more than two years ago have between 8 and 511 solid-state drive capacity.
+3 More reasons against
Only One USB 2.0 Port
The Zbook 15 is a one USB 2.0 port notebook PC. Most of the other portable PCs of a similar spec and age to the Zbook 15 have between one and two USB 2.0 ports.
Only 4 Bluetooth Version
This notebook PC supports a 4 Bluetooth version, which is the most commonly supported Bluetooth version on laptops of a comparable age and type to it.
6 Other reasons to consider the HP Zbook 15
Released Over Two Years Ago
HP released the Zbook 15 over two years ago.
Average Internal Memory
The Zbook 15 has a pretty standard internal memory (8 gigabytes) compared to most of the other notebook PCs of this age and spec.
At 2.8 kilograms, the Zbook 15 has a fairly average weight compared to most of the other many processor core portable PCs that have been available for around the same time as the Zbook 15.
If you would consider a portable PC with a heavier weight then you might want to look at the Zbook 15 (£552.20) (2.8kg), or the Zbook 15 (£1,331.32) (2.8kg) both from HP.
+4 Other reasons
Average Screen Size
The Zbook 15 has a relatively typical screen size (15.6 inches) compared to most of the other similar spec portable PCs that are a comparable age to the Zbook 15.
Average Total Storage Capacity
The HP Zbook 15 has a fairly typical total storage capacity (750 gigabytes) compared to most of the other comparable spec laptops that have been around for a similar time to the Zbook 15.
We compared this notebook PC to all the other 750GB total storage capacity notebook PCs and we think because of it's better review score, the HP Pavilion 17-e118dx is also worth considering.
HDD Storage Medium
This notebook PC has an HDD+SSD storage medium, which is the most commonly found storage medium on many processor core portable PCs that have been around for more than two years. HDD is a traditional storage drive which stores the information on magnetic disks. HDD drives are slower than other forms of storage such as solid state drives (SSD) and flash drives.
