ASUS Chromebook CX15
Ranked #3 in Best Chromebooks Under $500
ASUS Chromebook CX15
$199

The CX15 is the budget pick. $199 for a 15.6" 1080p Chromebook makes sense for first-time buyers, students, and grandparents who do email and browsing. Outgrown faster than every other pick if your tab count exceeds 10.

Strengths
  • 15.6" 1080p display — largest screen in this lineup
  • Cheapest pick at $199 — best budget Chromebook for first-time buyers
  • 10-hour battery
Watch-outs
  • Intel Celeron N4500 is slow — fine for browsing, struggles with 10+ tabs
  • 4GB RAM (not Plus tier) — multitasking hits a wall
  • Plastic build feels lighter-duty than every other pick

Higher ratedRanked #1 in Best Chromebooks Under $500
ASUS Chromebook Plus CX34
$449

The CX34 is the best-overall Chromebook under $500. Chromebook Plus tier means Google's higher hardware floor — i5 CPU, 8GB RAM, 128GB SSD — which puts it ahead of bargain bin Celeron Chromebooks. Best for everyday productivity, browser-based work, and student use.

Strengths
  • Intel Core i5 (12th gen) — most CPU horsepower at this price
  • 14" 1080p IPS display with anti-glare coating
  • Chromebook Plus tier — Google's premium spec floor (8GB RAM, 128GB SSD minimum)
Watch-outs
  • Plastic chassis trails MacBook-grade ultrabooks on feel
  • No backlit keyboard at the base SKU
  • Speakers are functional, not impressive
