I'll answer my own Q in case any one else is looking at this.
Very happy so far, excellent quality on scans from photos, documents, plus 35mm negatives and slides which is 50% of what I bought it for.
It also comes with a free version of ArcSoft Photo Studio (version 4), which from what I can see is very capable and for my infrequent/untutored uses, probably just as good as Photo Shop elements which I was going to buy for about £50 but now I'll give photostudio a good try out first.
Only downside is that this is a beast of a scanner, its neither lightweight or small like my previous slimline Canon 'lide' scanner, its not going to inconspicuously sit on your desk, and its inconveniently (for me) long at 48cm (my canoscan is 37cm, barely larger than A4). Its also wide at 28cm wide, and high at 10cm . It has the power "brick" converter built in which probably adds to the considerable weight, think I'd for once have preferred it separate !
However, if you are looking for more than a document scanner, an affordable way to scan negatives and slides at under £100 (£90 on Amazon, where I bought it) this is definitely worth considering since the next step up seems to be a Nikon dedicated negative scanner at around £500.
For ordinary photo/document scans its pretty quick, for 35mm film negatives and slides its as slow as all scanners seem to be from what I read, around 6 minutes to scan a singke 35mm neg at 4800DPI (highest res on film), 3min at 2400. When zoomed in to extreme magnification 4800 is better than 2400 so it is worth it for archival purposes, though I doubt you could tell any difference at anything smaller than say 8 x10 print size.
