First IBM computer to use the 3.5" floppy disk?
[edit]If the PC Convertible was released in 1986, it's not the first IBM computer to use the 3.5" floppy disk. The IBM JX, while not seeing a world-wide release, even had dual 3.5" floppy drives already in 1984. 80.187.100.92 (talk) 11:57, 2 December 2014 (UTC)
Wrong history
[edit]2nd paragraph: It was the follow-up to the IBM Portable and was model number 5140. It was replaced in 1991 by the IBM PS/2 L40 SX,
That is not right. In May 1989 IBM announced the IBM Model P70 (named "Personal System/55 Model 5545T" in Japan), followed by IBM Model P75 in Novenber 1990 and L40SX in 1991. - So written in the book "ThinkPad A Different Shade of Blue". --91.12.107.160 (talk) 22:03, 21 March 2015 (UTC) (Mornsgrans)
Predessecor
[edit]I would not call a non laptop computer the predessecor to the first IBM laptop. I think this should be changed. If I am wrong I apologize. ~2026-24819-87 (talk) 16:54, 22 April 2026 (UTC)
- The notions of "predecessor" and "successor" applied to computers is a weird obsession of the infoboxes on Wikipedia. It's not strongly defined and often presents a confusing history of development of a product line, especially when the sales life of machines overlap. What do we mean by "predecessor"? This was the first laptop 5150-compatible made by IBM and so had no predecessor IBM-made laptops compatible with the 5150. It's clearly meant to use the software of the original desktop 5150 and the luggable 5155 and survived after these types were discontinued so it succeeded them. What are we trying to convey to the reader by the idea of "predecessor" and "successor" machines? You could even argue the 3 1/2 diskettes made it *in*-compatible with the 5150 and 5155. More than one user was frustrated trying to bring her field notes back to the office, I'm sure. --Wtshymanski (talk) 19:29, 22 April 2026 (UTC)
