Lenovo Legion Go S Review: SteamOS Without the Valve Price Tag

The Lenovo Legion Go S ranks number 8 on Gavler's Best Gaming Handhelds list with an 8.4. Its headline achievement isn't a spec — it's a first: this is the first PC gaming handheld outside Valve itself to ship with SteamOS, trimming the original Legion Go's complexity into a more comfortable 8-inch shape. Windows Central named it the best mid-range handheld, and Tom's Hardware praised the software directly, calling SteamOS "far easier than Windows to navigate with controllers and a touch screen." The catch is that the price you see advertised and the price of the configuration reviewers actually raved about aren't quite the same number.

What it is

The Legion Go S is Lenovo's more approachable follow-up to the original Legion Go, built around an 8-inch, 1920x1200, 120Hz LCD screen — larger and sharper than the Steam Deck's panel, covering about 97% DCI-P3 at up to 500 nits. It's available in two configurations: a base model with an AMD Ryzen Z2 Go chip running SteamOS, starting around $599, and a higher-end Ryzen Z1 Extreme configuration tested up to $829.99. Both pair with 16GB of LPDDR5X RAM, 512GB of SSD storage, and a 55.5Wh battery rated for roughly four hours.

Being the first non-Valve handheld to officially run SteamOS is the real story here — it brings the Steam Deck's frictionless, controller-and-touchscreen-native software to different, arguably more comfortable hardware, which is a meaningfully different proposition than yet another Windows handheld competing on raw specs.

In use

The screen is an immediate, noticeable upgrade over the base Steam Deck's smaller panel — bigger, sharper, and brighter, which Windows Central cited directly as part of why it considers the Legion Go S the better screen. Combined with SteamOS's boot-straight-into-your-library simplicity, it's designed to feel as approachable as the Deck while looking sharper doing it.

Performance is where the two configurations diverge sharply. Tom's Hardware's assessment of the Z1 Extreme configuration was glowing: "some of the best SteamOS performance it has measured" — genuinely strong numbers for the platform. But that performance comes at $829.99, a price that puts real distance between it and the base $599 SteamOS model most buyers will actually consider. Tom's Hardware's own framing makes the trade-off explicit: "If money is no object and you want the best performance you can get with SteamOS right now," the pricier configuration delivers — a conditional recommendation, not an unconditional one.

The trackpad is the one component that drew consistent criticism regardless of configuration — reviewers found it finicky, which matters more than it might sound like given how much SteamOS's desktop mode leans on precise pointer input for things outside the Steam library itself. Battery life, at around four hours, is also on the modest side for the category, trailing the Steam Deck OLED in less demanding games.

Strengths

• First non-Valve SteamOS handheld. Brings the Deck's frictionless, controller-native software to different hardware — a genuine first for the category.
• Sharper, larger screen than the Steam Deck. 8-inch, 1920x1200, 120Hz LCD beats the base Deck panel on size and resolution.
• Strong value at the base configuration. The $599 Ryzen Z2 Go SteamOS model undercuts flagship handhelds while keeping the same easy software.
• Genuinely strong ceiling. The Z1 Extreme configuration delivers, per Tom's Hardware, some of the best SteamOS performance measured to date — if you're willing to pay for it.

The trade-offs — who should skip it

The base-versus-premium pricing gap is the thing to understand before buying: the $599 figure that makes this handheld look like a value play is the entry-level Ryzen Z2 Go configuration, while the performance Tom's Hardware was most enthusiastic about belongs to the $829.99 Z1 Extreme model — a nearly $230 jump. Go in knowing which configuration you're actually buying, because the two deliver meaningfully different experiences.

Skip it if a finicky trackpad or a roughly four-hour battery life are dealbreakers for your use case — both are real, consistently reported limitations, not one-off review quirks. And if raw power matters more to you than software polish, the Windows-based competition in this price range can outmuscle the base configuration.

How it compares

On the same Best Gaming Handhelds list, the Steam Deck OLED remains the reference point it's competing against directly — Valve's own hardware still leads on battery life for lighter games and has a longer software track record, though its 2026 price increase narrowed the value gap that used to clearly favor it over challengers like this one. The MSI Claw 8 AI+ sits one rank higher at number 7 with an 8.3, offering a bigger 80Wh battery and Intel Lunar Lake performance for $999 — more power and battery life, but back on Windows and its usual handheld friction.

The Gavler verdict

The Lenovo Legion Go S earns its 8.4 by doing something genuinely new — bringing SteamOS to non-Valve hardware — and backing it up with a screen that beats the device it's most directly compared against. It's a comfortable, well-priced middle ground, especially in its SteamOS configuration, for anyone who wants Deck-like software on bigger hardware. Just be clear-eyed about which configuration you're buying: the $599 base model is the value story, and the $829.99 Z1 Extreme is the performance one, and they're not really the same purchase.

Common Questions

Is the Lenovo Legion Go S worth it in 2026?

Yes, especially the SteamOS configuration. Windows Central named it the best mid-range handheld, and it was the first PC gaming handheld outside Valve to ship with SteamOS, which Tom's Hardware called 'far easier than Windows to navigate with controllers and a touch screen.'

Should I buy the base Ryzen Z2 Go model or the Z1 Extreme model?

It depends on your budget. The base Ryzen Z2 Go SteamOS configuration starts around $599 and undercuts the flagships, but Tom's Hardware measured some of the best SteamOS performance it has tested on the pricier $829.99 Z1 Extreme configuration — a meaningful cost jump for meaningfully more power.

How's the Legion Go S's battery life and trackpad?

Battery life is modest — around four hours on the 55.5Wh cell, less than the Steam Deck OLED in lighter games. Reviewers also found the trackpad finicky, which matters if you rely on it for desktop-mode navigation.
