Overview
Business convertible versus consumer convertible. I used the Lenovo ThinkPad X1 2-in-1 Gen 9 and Samsung Galaxy Book4 Pro 360 for three weeks each, running the same workflow: email, documents, video calls, presentations, and light creative work. The ThinkPad is built for enterprise users who type all day. The Samsung is built for people who want a gorgeous screen and pen input.
Quick answer: The ThinkPad X1 wins for business professionals. The Galaxy Book4 Pro 360 wins for students and creative consumers. The 32 GB vs 16 GB RAM split seals it for productivity users.

Keyboard and Typing
The ThinkPad keyboard destroyed the Samsung’s in daily use. Deep key travel, satisfying tactile feedback, and a layout refined over decades. I type 5,000+ words a day and the ThinkPad made every session better. The TrackPoint nub kept my hands on the home row for quick navigation. I missed it every time I switched to the Samsung.
The Galaxy Book4 Pro 360’s keyboard is fine. Acceptable travel, decent spacing. But it feels shallow and mushy compared to the ThinkPad. For email, notes, and casual typing, it works. For all-day writing, the gap is real.
Winner: Lenovo ThinkPad X1 2-in-1 Gen 9. Best keyboard in any convertible.
Display
Samsung wins this one. The 16-inch AMOLED at 2880x1800 with 120Hz is bigger, brighter, and more vibrant than the ThinkPad’s 14-inch OLED at the same resolution and refresh rate. Samsung’s display expertise shows: 120% DCI-P3 coverage, vivid colors, and perfect blacks. The extra 2 inches of screen space makes multitasking with split windows genuinely comfortable.
The ThinkPad’s 14-inch OLED is still excellent. 100% DCI-P3, great contrast, accurate colors for presentations. But smaller and less impactful side by side.
Winner: Samsung Galaxy Book4 Pro 360. Bigger and more vivid.
Performance and RAM
The ThinkPad runs Intel’s Core Ultra 7 265H with 32 GB of RAM. The Samsung uses the Core Ultra 7 258V with 16 GB. For basic productivity, they feel similar. Both handle browser tabs, Office, and video calls without trouble.
The 32 GB versus 16 GB difference showed up during my heavier multitasking sessions. I had a large spreadsheet open alongside Teams with screen sharing, fifteen browser tabs, Outlook, and OneNote. The ThinkPad handled it smoothly. The Samsung started to hesitate. These aren’t synthetic benchmarks; this is how I actually work.
The ThinkPad also ships with Windows 11 Pro, which includes vPro support for enterprise IT management. If your company manages devices centrally, this matters.
Winner: Lenovo ThinkPad X1 2-in-1 Gen 9. Double the RAM and enterprise features.
Battery Life
The Samsung’s 76 Wh battery outperformed the ThinkPad’s 57.6 Wh by a wide margin. I got 9 to 10 hours from the Galaxy Book4 Pro 360 during mixed productivity. The ThinkPad gave me 7 to 8 hours. That’s a meaningful gap. If you spend time away from outlets, the Samsung lasts noticeably longer.
Winner: Samsung Galaxy Book4 Pro 360. Two extra hours per charge.
Build and Durability
The ThinkPad has MIL-STD 810H certification. I pressed, flexed, and stressed both chassis. The ThinkPad felt rigid and unyielding. Carbon fiber and aluminum construction at 3.17 lbs. The Samsung is light at 3.44 lbs with a clean aluminum build, but it flexed slightly under pressure. Not alarming, but noticeable.
The ThinkPad includes two USB-A ports alongside Thunderbolt 4 and HDMI 2.1. Legacy peripheral support matters in office environments. The Samsung trades USB-A for a microSD slot.
Winner: Lenovo ThinkPad X1 2-in-1 Gen 9. Military-tested durability and better enterprise connectivity.
Pen Input
Samsung includes the S Pen with 4096 pressure levels. Good for notes, annotations, and light sketching. No built-in storage, though, so it magnetically clings to the side and falls off in bags.
The ThinkPad supports Lenovo’s Precision Pen 2, sold separately. Similar performance once you have it. But paying extra stings.
Winner: Samsung Galaxy Book4 Pro 360. Included pen is a real value add.

Verdict
I’m recommending the Lenovo ThinkPad X1 2-in-1 Gen 9. The keyboard alone justifies it for anyone who types professionally. Add 32 GB of RAM, MIL-STD 810H durability, Windows 11 Pro with vPro, and two USB-A ports, and you have a convertible built for serious work. The smaller battery is the main compromise, but 7 to 8 hours still covers most workdays.
The Samsung Galaxy Book4 Pro 360 is the better pick for students and creative consumers who want the bigger, more vibrant display and included S Pen. It’s a great 2-in-1. But the 16 GB RAM ceiling holds it back for professional multitasking.
