12. Conclusion

As the comparison tests of the Dell Latitude D505 based on the Celeron M, or alternatively the Pentium M have shown, a notebook with a Pentium M CPU is only advantageous with regard to the battery life. Regarding performance, the difference for day-to-day use of CPU models with a similar core clock speed is only marginal.

Price-wise, it can be argued that one hour more battery life for a cost of $100 isn't much to pay. However, if a long battery life is really the premise, then in the case of the D505, we would rather invest $130 in a spare battery for the Celeron M. That way you can easily achieve an additional two hours of battery time. And, it only costs $30 more than a Pentium M system with comparable performance. If on the other hand, the premise is to have long battery life including the lowest possible weight, or in other words, the greatest mobility, then there is almost no way of getting around the Pentium M. But also in this case, it still doesn't have to be a Centrino notebook. After all, other suppliers also provide competitive WLAN modules.

Whether a Celeron M or Pentium M processor is selected, we rate Dell's Latitude D505 as a good business notebook, above all because of its great connectivity options, the numerous expansion possibilities and the attractive price. However, we weren't convinced of the quality of the PC's case and body workmanship.
