About the performance of the K1 I do not have to say much.
Advantages of the Shield Tablet:
Nvidia Game Stream, Shield controller, external HDMI output, stylus, stereo speakers
Game Stream: works well, who does not just CS: GO plays or any fast shooter who gets with Game Stream entirely new possibilities (play on TV or tablet). 5GHz WLAN or LAN necessary.
Shield Controller: High-quality controller, very well integrated into the system. With its own terminal for headphones.
HDMI: HDMI output correctly, no increased latency as with MLP HDMI.
Stylus: Works very well, Fingereinganbe can be manually disabled.
Disadvantages:
- Android 5.0 laggt. It does not feel liquid on
- Tegra K1 drawn heavily on the battery, you're at the games, milling (nvidia dabbler) or watching movies.
- Stability: Tablet depends in standby like to times. It sucks the battery before empty completely. Otherwise, it comes often to freezes while streaming.
- Hardware: The first batch all corners are torn in 16GB, 32GB, and the tablet after some time. If the environment is very quiet, you can hear crackling the capacitors in the device and cheep. From the speakers you can hear a faint noise.
Conclusion: So concept study a great tablet. Unfortunately, there is a lack of quality in software and hardware. Who takes the consciously accepted, get a great tablet with plenty of performance at an affordable price. All others I advise against the purchase. Nvidia tries since the market launch in the problems to get a grip, it has still not managed, however.
