good/bad HP Chromebook 15" Intel N200, 8GB DDR5 RAM, 192GB Storage
Capacity: 64GB eMMC+128GB SD Card
As I just received this Chromebook this is my review. Likes: its much faster than my old Chromebook which is a Acer about 10 years old. I like the big screen vs my old 14". good color and definition. HATE:The lightly colored letters. It is near impossible to read in low light and even in medium light. I have already ordered new stick on letters to make it more visible. HP you should have done a better job than this. This really detracts from the enjoyment of using this Chromebook. It is terrible. I can't give it 5 stars because of this problem.I would have liked another port for plug ins like mouse or thumb drives. Otherwise I love it.

Excellent for the price!
Capacity: 64GB eMMC+128GB SD Card
So far so good. Considering I got it primarily for browsing and smaller tasks, it's worrying perfectly so far. Boots up very fast, runs very smooth, and so far I'm happy with the battery life. I do wish I had thought about making sure it had a keyboard light but that's still mostly not a problem for me. I also like how simple it was to set everything up and get it synced with my google account and phone.

Good product

Chromebooks are a great concept. They're laptops without the bloat.

Glorified toy
Capacity: 64GB eMMC+128GB SD Card
Two issues:
The screen colors change with the slightest move of your head.
The scrollbar sometimes disappears. More importantly, it must be clicked on perfectly.
Amazon is refunding entire amount back to my card.
