Yes, the .doc extension is a standard Microsoft Word file extension, although the new format uses .docx. When you're using LibreOffice though, by default it will save to its own format as .odt. To change so that it always saves to a Microsoft format (for working with others), go to : Tools>Options>Load/Save>General>Document type .. Always save as or Preferences... -> load/save-> general -> always save as -> choose Saving Documents by Default in Microsoft Office Formats

Snidley gave good advice. I agree with just about all of it. You're not going to tax the performance of any modern machine you buy with the uses you specified. My one recommendation, and what I do every time I buy one or set one up for someone is to max out the RAM as much as possible. Fill open slots at least with highest possible. RAM will do you more good than CPU power in about 90% of all cases I've seen. If you buy from a computer shop they'll usually let you buy enough RAM to max it out and credit you for what's in it. Often there will be, for instance a 2gb when the slot will handle 4 so you have to remove it. Cheaper machines often only have 2 slots. For me, I quit using the tablet, partly because it died but partly because it's just not convenient. I bought a $20 smart phone to use as a mini tablet when I'm out and about. Works fine for me. I much prefer the keyboard and 17" monitor features on a notebook/laptop. It's my primary computer. I'm probably going to get another in the next month or two. I was looking at a refurb Toshiba for about $350. Everything I needed and more. Like I said I'd then add some RAM which I haven't priced but should be less than $100. Occasionally you'll see places that include office in their packages, however it's not "free". Technically, no extra charge, but they charge you a few hundred more for the package so, you still wind up paying for it. Most everything sold now should be compatible for Win10 unless you buy something old. Doubt you will. My needs aren't the same as yours although we do use them similarly! Brand, well other than HP/Compaq I wouldn't object to most any. Dell at the bottom of the barrel. Much depends on luck and how you treat them. Look for the features you want. Number of USB ports, etc. For me, a modem is required and few if any notebooks have them anymore so I have to dedicate a port to the modem. I always use a mouse so there goes a second one. I use an amplified speaker powered by USB so there goes another. Historically I too like Lenovo and I've had great luck with Toshiba but haven't dealt with them now for a long time, except my first one (13-14 y.o.) is still going strong. I had one that died. Still the overall quality of them were far above others. But YMWV. (Second to )Last comment: I do not hesitate to buy refurbs. They're often only slightly used if used and almost always a great value. OH, and DO NOT get misled by some of these places that include "$2000 worth of FREE software!!!" Most of it is available free anyway, such as firewall, anti-virus, anti-malware, etc. NOW, for last comment, check your software that you find absolutely essential and see if it's compatible with the OS you're getting. Probably should check to make sure it will work with Win10 since it will be force loaded on you unless you take action to stop it. I lost use of some essential programs going from Vista to 7 so I keep the XP unit around for when I do desktop publishing which isn't too often but still needed. Good luck in your search.

People are giving me a lot to think about. And I did broach the idea of a lift to DH. The lot is just over half an acre--150x160. For what it's worth, I've been watching the expanded northwest/west Chicago suburban area for homes with extra large garages (or both an attached and detached garage). There aren't many and they disappear fast. They will only appeal to a certain market, but to that market, they're in high demand. (Car collectors, people who have a hobby that requires a large workshop) As for garages in the neighborhood, the few existing homes have 2--several with an additional detached garage. The new homes mostly have 3--and a few have 4. I know it's not what everyone would do but that's one of the reasons to build instead of buy--because we can plan for the things that are important to us, even, or especially, if they're not commonly available. But when it comes right down to it, few of us only have as much house as we "need". I *need* a place to sit with a computer. I want it to be comfortable (desk with pullout keyboard tray), and I want a window to look out of, and I want to have nice furniture in it. I don't need any of those things (although my chiropractor might make an argument for the keyboard tray). But I want them and can't think of any reason why I shouldn't make them happen. We're all different--there are those on this board who prefer jack&jill bathrooms. I hate them. There are those who think a 2nd sink for a hall bathroom shared by kids is a waste of money. I disagree (and so would my kids)--but that's okay. We want a house with a large double shower and don't care at all about a soaking tub. Someone else wants that tub enough to devote 36 sq ft to it. That's all okay. Looking at houses on-line, I saw zillions of "newly remodeled kitchens" that I hated. Some were objectively bad designs. But most of them weren't--they were just finishes that I didn't like at all--and knew we'd pay a premium for that 'newly remodeled kitchen' even though I'd want to rip it all out. It's all part of why people build instead of buy. We want what we want--and some of us are fortunate enough to be able to make that happen.

I agree with many of you who installed the free Libre Office suite. It's similar to my favorite MS Office 2003 with drop-down menus and toolbars you can customize. It will allow you to open MS documents, work on them, and save in the same format. It's also a breeze to save documents in the PDF format. There is a slight learning curve in Libre, as the names of some of the functions had to differ somewhat from Microsoft. However, what angered me most about MS is when they stopped offering support for either an operating system or office package in order to force one to purchase a new computer. For me, the ribbon menu was the last straw. In Office 2003, I knew exactly where every command was located. When they changed to the ribbon, a 15 minute job turned into hours trying to locate the command I needed. And I sorely missed the ability to create my own customized toolbars and menus. So I got a Mac, installed Libre and really love both. When Apple updates its operating system it's not a big deal. Just a simple download with no glitches and no nasty messages that support will soon end. I used to dread it whenever I had to download an update or upgrade the Microsoft system, for every time this happened the entire process was a nightmare. I'm really glad I made the move to a Mac, but it's a shame that MS shot themselves in the foot by refusing to back up their products or listen to their customers.
