When choosing between the Eluktronics RP-15 and the Lenovo ThinkBook 13x, consider that the RP-15 typically offers better performance for gaming and intensive tasks due to its dedicated graphics and higher-powered processors, but it's usually heavier, making it less portable than the ThinkBook 13x. The ThinkBook 13x, on the other hand, is sleeker and lighter, making it more suitable for travel and everyday use; however, it may not handle demanding applications as well. Battery life often favors ultrabooks like the ThinkBook, which is something to keep in mind if you're frequently on the move without access to an outlet. Give Feedback

Hardware Canucks

Eber Anthony | October 2020
"To conclude, I’m genuinely impressed with Eluktronics and what they have been able to deliver with the RP-15. You see this is all about maximizing performance, cooling, and giving users the most flexible I/O, and then wrapping it into a chassis that doesn’t feel super cheap. Let’s also not forget the price point, I think they have really nailed it in that department."
