Our take on the HP 17-cn3145ds 17.3" HD+ Touchscreen Laptop

The HP 17-cn3145ds is a large-screen budget laptop built around Intel's entry-level N100 processor, 4GB of DDR4 memory and a 128GB UFS drive. The 17.3-inch HD+ touchscreen gives it a roomier display than most budget 15.6-inch rivals, which is its main draw. The N100 and 4GB of RAM suit web browsing, email, streaming and light office work, not heavy multitasking or gaming. Windows 11 in S mode limits you to Microsoft Store apps until you switch out of it.

Questions and answers

Is the HP 17-cn3145ds good for everyday use?
Yes for browsing, email, video and word processing. It is not suited to gaming, video editing or many apps open at once.
