30 secs. that's impressive
no, 10s would be impressive and wouldn't be.
My Mac boots in under 30 seconds and that's quick enough for me
Actually anything Less than 15s would be impressive, which would usually imply SSD. About 3 years ago I wiped a new Win 7 laptop (regular HDD) for a friend, it was taking nearly 90s. After a properly configured XP install it was 20s.
My Oldest XP Laptop* had its XP re-installed once, in June 2002. It still boots in 45s. Not too long to wait. Oddly the much newer laptop (several years old, got S/H) recently set up with Linux Mint and Mate Desktop) also takes 45s. I may upgrade HDD in it. My Netbook takes about 20s, it's using a 32G Compact Flash card instead of an HDD. Much slower to write to.
Boot time of itself doesn't mean much without knowing type of disk and configuration. Also personally, it's irrelevant. I boot two laptops at 7.25am and go make cups of tea for me and Mrs Ray. Then I log in. They are not turned off till about 11pm, or sometimes 3.30am if I'm on a writing binge.
[* Pretty much used 5 to 12hrs a day every day, on it's fourth battery pack, 2nd keyboard and second casing last year donated by a scrap machine bought for £10, 1600 x 1200 ultra sharp, 1.8GHz, yes it's over 13 years old! Only three months ago replaced by a Linux Mint Laptop for Internet etc, I'll still use it for XP stuff that has no Linux alternative or doesn't run on Linux's WINE]
