I've been tuning since 2004 and have never paid more than $150 for a tuning laptop. Started with HPs running Win XP. Realized they were junk with shitty hardware. Hinges constantly breaking. Then switched to Toshibas. I have one Toshiba with Win 7 that I've been using for probably 7-8 years. Maybe longer. It's a tank. I've replaced the battery once. I have a few Dells too that seem to be very reliable. With Dells stay with the Latitudes rather than the Inspiron as they are business models and are built better. I look for Dells now about 3-4 years old on Craigslist and pawn shops and can usually find one in good shape in the $150 range. These laptops are dedicated to tuning only. No other uses. I prefer ones with Win 7 even though it not supported my MS anymore as software like Tunercat OBD1 and 2 just runs better on them. Even if they need a new battery they are pretty cheap on Amazon.
