Hello people. I'm currently "restricted" to using a very old notebook. I sold my old Acer one and my new HP one got too hot due to fabrication issues (still waiting for HP to replace it). This very old notebook has the following specs: - Intel Celeron 1.73 Ghz - 512MB DDR2 of RAM (128 MB shared for Graphics) - 78 GB Seagate SATA Obviously, this piece of hardware can't properly run any modern OS. And then, Microsoft WinXP Pro SP3 "suddenly" became the only reasonable option. During these days, where the need to tweak every bit of what is tweakable raised - manually and with several third-party softwares - thanks to incredibly poor performance issues, I also tested some of the most famous browsers, with only two plugins installed (Flash Player and Silverlight). IE 8 , Firefox 3.6, Firefox 4 Beta , Opera 11, Google Chrome Stable, Canary Build, Avant browser. Portable and Installed editions. My personal test proved (at least to me) that they were all really made to run on modern hardware. The number of performance issues I ran in on all of them was astonishing.... for example, try to load more than 6 resource intensive tabs on them with such an old piece of hardware. It's a nearly impossible mission. Then I tested K-Meleon 1.6. It was blazing fast, very customizable, feature rich and, most important, never crashed (even with several resource intensive tabs opened). I guess I needed to make some justice to it and "recommend" it to others. K-Meleon is very lightweight and covers all the basics of browsing, with good native handling of bookmarks, RSS feeds, spellchecker, "on-demand" plugin activation, fast rendering engine, native user-agent spoof of common browsers for bonus compatibility and many more. Really worth a try. -------------- As a side note, foobar2000 also proved to be the best music player option for my new temporary "special needs": it simply handles system resources way better than WMP 11, is spartan but very organized and its foo_wlm plugin works like a charm.
