I'll chirp in, had all types of laptops over the last 10 plus years and used them all. Highlights of my experience:
1. Toshiba, paid over $3,000 about 4 years ago, top of the line, needed two hard drives in two years, always crashed. Good thing I had warranty at FS, but it needed over a month each time to fix it and no laptop. Never buy Toshiba again. Toshiba used to be the best laptop over 15 years ago, it's lost it's lustre, not that great any more.
2. IBM thinkpad are built like Mercedes, still have it and after 10 years still runs great no mechanical problm, however can't upgrade to today''s standards. Lenovo, not as well built, but still above average nonetheless.
3. HP is not my cup of tea, poor keyboard desin for my liking and most unstable of the laptops I had. I had to reformat the hard drive twice in two years. Maybe bad luck, but I'm jinxed now.
4. Dell business models are great,had it for 3 years no problem and still running great. Best thing about Dell is its warranty, get it, well worth it. If you have an issue, they will replace it in a few days, no questions asked, make sure you get the top warranty offered.
5. Mac's are great but has limitations, titles available, etc.. Great for graphics, great looks, well built, a bit over priced.
6. Sony, way over priced and not stable, Acer is well priced, but not as well buit and not for the long haul. All other no names, stay away.
That's my life experience, I now have a Dell Latitude for business and Mac for fun and games.
