Okay, this is going to be a strange post, but let me know alternative thoughts before the whole plan ends up in a spiral like my schemes usually do... I bought a Q550 about 7 months ago now and I ended up relying on it for 90% of my day-to-day needs. I originally thought it would be a companion to the T580, not a replacement. Well, that changed as I started using it and I found out that it is more than capable of the 'normal stuff' I threw at it. It became my only computer in use for a long time. Well, I recently hit a wall with the Q550. While TurboCAD, PaintShopPro, OneNote, and most of the other Office programs run just fine for photo manipulation, light CAD use (all my comparison drawings are done on the Q550), and all my notes and documents, I ran into situations recently that changed the equation. I hit a wall with the Q550 about 2 months ago, so after 5 good solid months of this being my 'only' computer I found it incapable of some intense stuff..the Girlscout Troop needed to do some video work and the Q550 was not up to the task; that was just the start. I resurrected the T580 from the cabinet like I intended for it if I ran into this situation, set it up on the desk with a large monitor, keyboard, and mouse and the girls went at it. The T580 did well. Recently I ran into another wall and this one is a bit bigger. This time the limitations came from a surprising source...I loaded Visio and that runs on the Q550 like a one legged dog. In addition, graphics intense PowerPoint chokes the thing as well to the point of lock up. I tried taking my T580 to work to do these functions and it did the job just fine, but after using the 16:10 screen of the Q550 I have found that I detest the 10.1" 16:9 screen on teh T580. It looks like I need a bit more power for about 10% of the time, but I also want a larger screen. So, scheming time... My 2730P is in use so my C2D is busy. So I am thinking about one of the following to replace the T580, and yes, I would sell this one and not just toss it in the cabinet like all the others, but I did get rid of the LS800 this year....that is a big step forward for me. - HP 2760P - fast, I am used to it, but expensive and I would need another base and slim battery again since the setup I had is in use and going away again shortly to college. Super big $'s, but I do consider this machine to be the best in class of the powerful convertibles. - Fujitsu T730/T731 - fast, bigger and heavier than the 27xxP but integrated with a DVD. No base needed, but I would want the port replicator for my desk, and the expansion bay battery eventually if I go mobile. More expensive than the 27xxP when new, but surprisingly cheaper when used. The screen is the same size as the 27xxP, but surprisingly, only a little less weight than a T900/T901. - Fujitsu T900/T901 - fast, way bigger than big (still a smaller screen than my old laptop), and integrated with the DVD and drive bay battery like the T730/T731, in fact, they are the same. Very expensive new but the cheapest of all of them used and I assume that is due to the bulk. - Get a used cheap laptop - probably the cheapest way to get power and retain some mobility, but I would not be excited about it. So, the scheme would be to opt for the T900/T901, get a port replicator, and then use that on the desk and/or brief trips when needed for the 10% of the time I need more mobile power than the Q550. In effect it would become the Thinkpad laptop I used to have going back to my TC1100 days where the TC1100 was my note taker and the Thinkpad was my workhorse. I would then sell the T580 and TC1100 and regain some file cabinet space. Any opinions?
