Does this thing actually work or is it just hype?

It works about 60% of the time on simple stuff, 20% on complex workflows. The demos look amazing because they cherry-pick the successful attempts. In production, you'll spend more time debugging failures than celebrating successes.Real example: Our QuickBooks invoice automation works great until a "Your trial is expiring!" popup appears and Computer Use clicks "OK" instead of "X", upgrading us to a plan we didn't want. Cost: $300 charge + 2 hours on support calls.

How much will this actually cost me?

Way more than you think. I budgeted $300/month, spent $2,100 in 3 months. Failed attempts cost the same as successful ones. A single buggy workflow can cost $200+ in a day if it gets stuck in retry loops. - Light testing: $100-400/month - Production use: $800-3000/month - Heavy enterprise: $3000-8000/month

Why does everything take forever?

Because Computer Use has the attention span of a goldfish and the hand-eye coordination of a drunk toddler. Every click requires a 5-second existential crisis: "Am I clicking the right thing? Should I take another screenshot first? What if there's a popup?"I timed a simple "update customer address" task: Human = 1 minute, Computer Use = 18 minutes. It took 47 screenshots and still got the ZIP code wrong. That's like watching someone parallel park by taking a photo, thinking about it, moving 2 inches, taking another photo, thinking some more...

What breaks most often and drives you insane?

**Popup dialogs are the devil**. Any modal, cookie banner, or "Rate our app!" dialog makes Computer Use lose its shit completely. I've watched it click random spots for 5 minutes straight when a Windows update notification appeared. **Loading animations**: Computer Use has zero patience. It'll click "Submit" while the page is still loading, or try to fill forms that haven't rendered yet. Timeouts are your friend. **Dynamic layouts**: Anything that shifts content after page load breaks coordinate calculations. Social media sites, modern web apps, anything with infinite scroll = guaranteed failures.

Is this better than just using Selenium or traditional RPA?

**For legacy systems**: Hell yes. Our 15-year-old ERP system has zero APIs and a UI built by sadists. Traditional automation breaks when they patch anything. Computer Use adapts. **For modern web apps**: Absolutely not. Selenium is 20x faster, 10x more reliable, and costs pennies vs Computer Use's dollars. Only use Computer Use when APIs don't exist.

Can I actually use this in production without getting fired?

Only if: - Your boss is cool with unpredictable monthly bills - The process isn't time-critical (Computer Use can take an hour for 5-minute tasks) - Someone monitors it daily for failures and cost spikes - You have fallback procedures when it inevitably shits the bed Best for: non-critical automation, legacy system integration, testing workflows Worst for: anything time-sensitive, high-volume processing, mission-critical tasks

What's this security nightmare I keep hearing about?

[Prompt injection attacks are real](https://www.prompt.security/blog/claude-computer-use-a-ticking-time-bomb). Malicious websites can literally control Computer Use by hiding commands in page content. It'll click things, download files, or navigate to sites based on hidden instructions. Solution: Run everything in isolated VMs with no network access to production systems. Treat Computer Use like malware - because it basically is when compromised.

Why does my 4K display make everything worse?

Computer Use's coordinate math assumes standard resolution. On 4K/5K displays: - Clicks land 20-50 pixels off target - Screenshot processing costs 3x more tokens - Success rates drop 30-40% Mandatory fix: Set display to 1280x800. Yes, it looks like 2005. No, there's no better solution yet.

Should I wait or start using this now?

**Wait if**: You need reliability >90%, sub-minute task completion, predictable costs, or your job depends on it working. **Start now if**: You love bleeding-edge tech, have budget for failures, work with legacy systems, or want to impress people with "AI automation" demos. Reality check: Computer Use will get better, but the fundamental screenshot→think→click→repeat approach will always be slower and more expensive than purpose-built automation.
