Hi Leon,
As far as Apex sketching goes, it is a relatively light program with regards to resources when compared to the likes of a "full 'forms' program" like any of the recent mainstream programs by ACI, ALM, Bradford, SFREP, etc. This is to be expected, given what all a "full forms program" does. Still, none of them are what one would describe as being particularly optimized for mobile devices. But, again, they don't usually have to be since they are written primarily (or, in some cases, only) for use on a desktop machine. Mobile devices are by their very nature, lighter in specs and that can make a difference when you try and use a "full program" in the field. That is one of the issues when using Windows Tablets - folks seem to expect their little tablet to somehow hold its own compared to their monster desktop system. Logically, they (should) know it can't, but they still try and then can get frustrated. So, as long as you don't expect your $350 device to handle the load that your desktop system does - that is, don't throw a bunch at it - you should be fine.
So, with some of the earlier tablets (including the Dells), you need to look at the amount of RAM on the device, the capacity and type of hard drive and then work within their limits (and the available screen size, etc.) If it is JUST (or even mainly) for use with Apex, you can get by on a machine with 2 GB of RAM. If you start trying to run a full desktop program (that likely struggles from time to time with 4GB anyway) and then try and run Apex in an integrated fashion through that other program, guess what is going to happen... Summarily, when a device runs out of RAM, it'll try to go to the HDD/SDD to use a sort of "virtual" RAM and when doing so, things can start to feel sluggish. Have you ever used ANY computer and said "Wow, this thing is just too fast!"?? LOL
So, does your Dell have 2 GB or more? Does it use a speedy SSD or is it using eMMC for storage. What are the screen specs - I know it is ~10", but what is the resolution/aspect ratio? What OS is it running - Windows 8.x or has it been updated to Windows 10 yet?
The Surface Pro is a fine machine and it has a superior aspect ratio. Generally speaking, the aspect ratio gets more important as the screen size diminishes. Of course, the SP3 and SP4 both have larger screens... The S3 (non-pro) has a more similar 10.8" screen but has a slower CPU and storage type than the Pro... BUT, given the price you are paying, I don't know that they are worth the premium (assuming the one you are getting is relatively new and in great shape.) I know it may sound counter-intuitive, but in many cases, if you are using it mainly for sketching in the field, and occasionally checking stuff on your "full forms" program, the newest Dell 8" may actually be a better fit due to ergonomics (easier one-handed operation), price, etc. If you are sure that nothing less than a
+10" device will work for you, something like the Lenovo ThinkPad 10 is a lighter device and should be available at a similar price (I think I paid about $550? for mine with 4G LTE when new) if you can find a "certified" refurb.
In the end, since you know the seller and it seems like it could be a low-hassle way to get going, I'd give the Dell a shot. If it works out, then great. If you like it but wish you had gotten a faster, or lighter (or whatever) device, you'd probably be able to recoup your purchase price easily and move upward, or whatever
Finally, remember that these are just MY thoughts, based on how I look at things. True, I have input from a very wide array of appraiser types, but what really matters is what works for YOU. In any case, you are to be congratulated for reaching out to your peers and trying to make the most informed decision based on input from others. We do this with other "market data" in our profession, so this approach seems logical for anyone with the appraiser gene, but I am surprised when some folks just rely on advertising vs. peer/user input. That is like getting your comps from listing info vs. confirmed sales data IMHO.
Hope this helps!
